Yeah, I get that, and it's less of a problem here, but it definitely annoys me when it does.
Slight tangent: I have discovered that I have to be really careful and chill out after a strenuous ride, because while I do get a terrific blast of endorphins, there's some irritability and paranoia that comes with that as well. I've actually had a lively discussion about this with college athletes I work with, and they report similar symptoms.
Sometimes, this is a very real concern, and sometimes it's totally in my head. Last week, I was convinced this truck was following me, and the driver was gonna do something bad as I wound uphill on winding canyon rounds at my usual 8 MPH in ECO and NORM. Because I was revved up and not thinking clearly, I decided to really pour it on. I was very surprised to find that even with my dinky little 40nm mid-drive motor, I could double my speed if I pedaled as hard as I could and then shifted quickly into high-- and I was able to maintain that higher speed with little effort once I got up there. At 16 MPH, the curves in the road are sharp enough that I could outhandle the truck. I pulled away from him. (And I burned a LOT of electrons. Tank was already low, but that was definitely less efficient, back of the envelope, that little sprint cost me a mile or two of range.)
And then realized I was just out of my mind, he wasn't chasing me at all.
A few days earlier, I found myself yelling at a few drivers who did California stops (e.g., only slowed down) at stop signs and then drove right in front of me. What jerks! How dare they! I have a bright front and tail light-- not extreme, but just bright enough for night-riding on trails.
Then, last week, the tables were turned and it happened to me when I was driving-- I didn't see a bike at a stop sign, despite their having perfectly adequate front and rear lights.
I definitely feel pretty silly after those things happen.
