Automated Safety Destroys Critical Decision-Making Skills

Time and again I see comments in support of software locked speed limits in e-bikes as a common safety measure.

Psychology begs to differ. Similarly to the way leg muscles atrophy when they aren't used, reduced exercise of critical judgment making results in reduced ability. When the bike takes control of speed, judgment critical to speed awareness is eroded. When that guy blows past you full speed on a narrow trail, one reason is that he has surrendered his own judgment to the bike to make those speed/safety decisions for him. In contrast, a biker who has to do the work of watching his speed limit is more situationally aware of and constantly making decisions about road conditions. Why make decisions when the bureaucrats have made them for you because you're too incompetent to observe a speed limit? Here is a psychological briefing on the matter that can be used at a professional level to make the point that the more automation we have in our lives the less able we are to exercise our own good judgment.

MEMORANDUM: THE COGNITIVE COST OF AUTOMATED REGULATION

SUBJECT:
The Paradox of Competence Decay in Firmware-Limited Mobility

I. EXECUTIVE SUMMARY

The current trend toward software-based speed regulation in personal electric mobility devices—specifically electric bicycles—is framed as a safety measure. However, psychological and ergonomic evidence suggests that these measures induce "Competence Decay." By automating speed decisions, we are shifting the rider from an active operator to a passive monitor, ultimately weakening the situational awareness and manual reflexes required to navigate public roads safely.

II. THE PSYCHOLOGY OF AUTOMATION BIAS

The primary danger of firmware-enforced speed limits is the phenomenon known as Automation Bias. Research in human-computer interaction and aviation psychology consistently shows that when a system provides a "safety net," human operators significantly reduce their own vigilance.

  • The Vigilance Decrement: As identified in classic human factors research, when an operator's role is reduced to monitoring rather than performing, their ability to detect anomalies drops precipitously (Warm, Parasuraman, & Matthews, 2008).
  • The "Nanny" Effect: When an e-bike’s firmware intervenes to cap speed, the rider stops internalizing the speed-environment relationship. They are no longer "reading" the traffic or the road; they are waiting for the software to signal the boundary. This removes the essential "feedback loop" between the human brain and the physical environment.
III. SKILL ATROPHY AND OVER-RELIANCE

The long-term cognitive consequence of this technological "coddling" is the atrophy of critical motor and decision-making skills.

  • The Transferability Crisis: We are observing a parallel to the transition to autonomous vehicles. Studies on "automation-induced loss of skill" demonstrate that drivers who grow accustomed to automated cruise control and braking exhibit slower reaction times when forced to take manual control (Endsley & Kiris, 1995).
  • The Illusion of Safety: By artificially capping performance, manufacturers create a rider base that is conditioned to perform within a narrow, "governed" set of variables. When the rider encounters a real-world scenario that falls outside the firmware’s parameters—such as an emergency obstacle—they lack the refined instincts to manage the bike’s momentum manually. They have been "trained" to be passengers in their own transport.
IV. THE DANGER OF "DE-SKILLED" RIDERS

The push for uniform, firmware-enforced speed limits creates a false sense of security that masks a decline in actual rider capability.

  1. Reduced Situational Awareness: Because the bike "takes care" of the top speed, the rider is less likely to actively scan for road conditions, as they assume the hardware will prevent them from reaching "dangerous" speeds.
  2. Increased Risk of "Surprise" Failures: A rider who has never learned to manage a high-torque or high-speed input manually is unprepared for the moment the software fails or is overridden by environmental conditions (e.g., downhill momentum).
V. CONCLUSION

From a psychological standpoint, the most effective safety feature is a competent, engaged operator. Any regulatory system that incentivizes the reduction of the rider's active role is inherently counterproductive. By automating the safety threshold, we are systematically disabling the rider’s ability to function as a self-sufficient operator.

We are trading individual competence for collective mediocrity—a trade-off that, in the complex environment of public roads, likely increases the risk of accidents rather than mitigating them.

Is there a bike with pedals that limits top speed?
Not arbitrarily, except of course for e-bikes with speed caps in the software. Fitness and the exact parameters of an ordinary bike have limits, of couse. But they are not artificial; they're baked in-- and the bike doesn't suddenly throw on the brakes, of course. Rode too fast and broke your arm becasue YOU CHOSE to ride too fast? You won't do that again, or at least not as recklessly. Broke your arm on a 20 m.p.h. locked e-bike? That was that unsafe bike's fault, not yours. It should have been locked down to 15 m.p.h. Then it would have been safe. My O.P. is about the psychology of not exercising one's own skills of judgment, not about exactly what any given bike can do. Not sure exactly what you mean.

That only restricts assist, not the riders ability to pedal faster.

In my younger days, we traveled low 20s on the level. I tried going over 20 on my Class 1 Gazelle. Failed 1st attempt. Pumped tires to max and hit 22 for about 5 seconds; probably wont do that again.

This thread is about the psychology of thinking something is safe because it has a built in device. It is not about whether any particular bike can go faster than 20 m.p.h. Of course they can. But a class two using throttle and not pedaling is in fact limited to 20 m.p.h. That doesn't make it safe, and the critical skills needed for safe riding are impaired by thinking that is the nature of "safe." Please stop discussing whether or not someone can go faster. If you are not familiar with these psychological concepts, maybe you should read the supporting research papers and then we can talk about whether built in safety helps riders develop their own safety instincts or not. I utterly fail to see your point in saying you could ride a bike faster than 20 m.p.h. I am neither saying that over 20 is unsafe or that under 20 is safe. I am talking about how your brain works, not how fast anyone can ride and whether that speed is safe or not. It's about having the judgment to be able to do that on your own. THAT is impaired by a built in speed limiter. You stop paying so much attention because the bike does it for you. I rode a budget Schwinn ten-speed down a semi-rural road at 60 m.p.h. downhill, (perfectly legal) when I was 10 and was terrified. No-one should do that, but it did give me a great instinct for when speed is getting out of hand that I will never forget.

Outside academic mumbo jumbo, do you think ebike riders actually think that a software speed limited motorbike with pedals is safe because of the limited speed? I suppose there are feeble minded people.
 
I might do an academic study on how quickly test subjects start mashing random answers to get it over with.

Do you agree with this statement.

today's ebike riders that learned safe riding because they were totally responsible for their decisions, no, I don't think they will or do. But a kid raised all his life that he has a "safe" bike becasue it makes choices for him he no longer can learn from?

If you are flying in a jet airliner, and the pilots have grown lazy and complacent because of automated systems, and then there's a glitch, is it still mumbo jumbo that the pilots never had the real skills of really good pilots in the first place? Really, if you're not interested in what happens in our brains when machines do things for us, this isn't your thread. Psychology is real stuff that doesn't become mumbo jumbo simply because you don't understand it or have no interest in it. Maybe spamming the page with irrelvancy will cause others not to want to post?

So the plan is to limit safety technology to keep our cognitive awereness at a level that outweighs the loss of automated systems.

This is a fine approach till the Deans daughter gets wiped out by a speeding bike and he orders everyone to revisit their conclusions.

Sounds interesting...but how to be sure they're just being random? 5,5,5,5,5 isn't really random. It's certainly not the answers someone has to think about to give. Unless the tricky test has "correct" answers, and they are all five. I did a bunch of MMPI II's with random answers. I've had to take a couple before in serious context, and told the test taker I was too familiar with it to answer the questions honestly. One agreed and just sat down and talked to me to evaluate me because I was right. The other didn't care, just going through the motions. You'll be pleased to note various computers say I am crazy 17 different ways, including mutually exclusive.

As far as plans, I don't necessarily have any and don't personally care about e-bike speed limits since I am a fully aware rider and that will never change, and currently have a 28 mph limit. That's workable enough, though I don't like it. Personally I care about motor power for purpose of uphill torque far more than speed. It's not about that. I just want people to be aware, especially those with kids who might not grow up with anything different. This technology is not as safe as it sounds. I admit I am annoyed when "safety" is more about other things, like making European bikes more marketable here. I think Americans should decide for ourselves what is safe. Dislike the principle, but I can live with 28 m.ph.

And yeah, about the dean's daughter. Human nature sucks. Especially knee-jerk reactionary human nature. Maybe we'll get lucky when he researches e-bike safety and he reads this thread.

Who is teaching kids what you describe? Do young parents these days really suck that much when it comes to teaching their kids? Who would teach that a bike is safe because of its software limited speed? Speed is one of many considerations in safe riding that need to be taught. Analog/ebike/moto all have similar safe riding considerations.

I think I learned to consider the speed thing at the school of hard knocks. It was a patch of loose gravel for bicycle and a pile of fish flies on a motorcycle.

Amazingly, dozens or hundreds of people on this very site claim that the speed limitation is a safety measure, and many want it reduced further so the bikes will be "safer." As far as what people teach their kids, you should consider that they also teach by not teaching, and they sure do not teach contrary to what they believe, so, maybe some of those exact parents are right here shouting that a built in speed limit is safety. I invite you to take it up with them. I don't think it will do any good.

Would you agreee the vocal group on this website is smaller than a bump on a gnat's butt compared to the population of ebike riders? I'd bet a very small percent of ebike riders know or care what these folks are talking about.

Can you point at someone making the claim that power limits/assist cutoffs/whatever are primarily a safety measure? They are almost entirely an access measure, because at their core, ebikes are motorcycles. They have two wheels and a motor, and most non-powered user groups are not interested in sharing spaces built for them with motorcycles. Various regulations regarding speed and power exist to create some sort of line below which its acceptable to enough people to treat ebikes as bicycles (and not motorcycles) for legal and access purposes.

I really don't care that you're not interested in the topic. I DO CARE that you're trying to convince me I shouldn't be raising the subject matter because you claim the numbers of people who do this here are "smaller than a bump on a gnat's ass." What about the mom of a ten year old who is pestering her to get him an e-bike and wants to think it over, comes here and a) has the misfortune of the bump on the gnat's ass thrown in her face and decides the bike is safe because of the built in speed limit, and fails to understand what that can do in her kid's head, she doesn;t know to teach about it becasue she doesn't know... OR she sees that AND my OP and sits her kid down and makes sure he is aware of and can make critical safety calls all on his own and the bike IS NOT safe becasue of this feature, and in fact, he can get killed on it at any speed. She might decide he needs a few more years of hard knocks on his ordinary bicycle first. That's her decision.

You DO understand that the posters are not the only ones reading? Right? That mom doesn't have anything to say, she just reads and goes and makes her decision.

Check the date I joined. I didn't make posts for six years. That mom whose kid just died because she didn't truly understand how to actively teach her kid didn't read my post because she saw you saying how stupid it was instead of going and finding somewhere you can be constructive. I care about that mom learning how she let her kid die (yes, grieving parents bend over backwards to blame their own inadequacies and things become crystal clear in hindsight) from the school of hard knocks. I felt the need to post a thread just so the warning is available to parents trying to educate themselves, and for those who also want to talk about it in a serious way instead of saying twelve times you ride fast and have had accidents. We know. I think all old school bike riders did, didn't we?.

Can we have your permission to proceed without the distracting nonsense, kind sir?
 
Zillions of ebikes in use here in coastal SoCal — many of them in the hands of teens and preteens with little training in traffic laws, basic bicycle safety, or the concepts of monentum and adhesion. A significant number of these riders clearly have no concept of "too fast for conditions" — especially the males. Ditto for some of the adults.

To a large extent, these folks have driven the public backlash against ebikes. And that backlash is driving the regulation.

What would YOU propose to do about that human side of the problem? Executive summary, please.

You just have to make everything a trail access issue, right? If you don't think anyone is saying the speed limitation is for safety, that's fine with me, stick your head in the sand. You are welcome to your narrow lens of trail access, and once again I appreciate your point. I do care about your views, but you know, in the last conversation we kinda went over that, and I asked you to consider my views and you just kinda quit talking. Perhaps I outwitted you with Quixoticisms? Nice talking points about the reason for the regulations, you are good at attenuating everything to your personal concerns. I'm beginning to suspect you're not a general advocate of equal access for everyone, just yours. I still don't understand why you think all the rest of the country needs what makes sense on trails but little sense in most other practical and utilitarian application. Like I said, it won't bother me if you get the feds to implement 3 class on any of their trails. It sounds workable for trails and the feds have the original access and use jurisdiciton to do what they want, so, I can't imagine a problem. What do you think of my problem unable to get up a hill with a 150 pounds of tools or material?

I'd mostly point to parental education. As far as the state, education, again. I have no problem with special ebike laws for kids that invoke civics as they go, no e-bike under 12, 12-15 a permit after they pass tests, class 1 or 2 (if we're stuck with it) Class 3 at sixteen again after passing tests, offering hands on e-bike safety classes. Use tickets to teach responsibility (yeah for the adult children too) and tell parents to make sure their KIDS pay the ticket. If things like that are happening, we could make sure that kids retain the mental skills they need. In the end what parents want taught to their kids is their decision, and there's no fixing stupid, so, I'd agree that there is little to be done as long as we are stuck with the locked speed limit except education and ticketing. At this point I am just raising the topic for discussion so it doesn't get overlooked, and hopefully thoughtful people could talk it over and come up with good ideas. A national dialogue about automation in our lives making us dullards would be great, but hey, Idiocracy was soft banned but became a cult classic anyway. Problem with us, we all think it's the other guy who walked straight out of Idiocracy.
