Wes, I need to tell you something about the drivers' perception of cyclists.
I had a number plate on the first incarnation of my 45 km/h e-bike, as it was registered as a moped and insured. Were it an ICE moped (we call it a scooter), any driver would recognize the scooter and understand ICE scooters must ride with the traffic (and are banned from bike paths). However, most of drivers could only see me as a pedalling person (read: a cyclist). I had many unpleasant situations being angrily yelled at by drivers. Most of them "didn't see" the number plate on my e-bike even if it was exactly the same as the ICE scooter one. Their perception was blocked against seeing the number plate on a bicycle!
More. I was stopped by police patrols twice. In both situations, I was riding with traffic where I had to be doing that, and intentionally was not riding on a bike path along the road. Each of those police checks took at least half an hour. It was because the only thing the police could see was a cyclist pedalling with traffic. Once the policemen were shown the number plate, a "witch trial" started. The police were very suspicious of the number plate ("Did you buy it in a flea market?") Then, I had to present my ID, so they could check my driving license, e-bike registration, and the insurance in their databases. When the documents turned out to be OK, my e-bike was undergoing a technical check: lights, horn, etc etc. ("Is your headlight Type Approved?"), and the best of all: 'Where are the direction indicators?" -- "The blinkers are optional on a moped, sir..." -- "Oh yes, I know, you may use hand signals; just checking if you knew it" the policeman said.
I do not need to mention some aggresive drivers and their verbal abuse, especially after I had shown the driver the number plate to them ("OFF ONTO THE BIKE PATH, FUCKER!!!")
It was a legal, registered, marked and insured moped but with pedals. Do you really think Wes an American driver would pay a slightest attention to your helmet blinkers? I know better ways to commit suicide...
