Im not trying to pile on here, but I drove behind someone in a brand new model Y today, on my commute to work (39 miles one way commute to work). They were coming from the same general suburban neighborhood I live in, and got off the freeway at the same exit etc. I was behind them about 20 ish miles of commute distance.
Their model Y was new enough that it still had the brand dealer temp plates on it.
They would jackrabbit off, then regen brake, then speed up too much , then regen brake. They had not figured out how to modulate the pedal well, and were braking because they were accelerating too fast, not because there was traffic in front of them.
The regen braking looked like a tap on the brakes, so the appearance was "accelerate..." brake light flick on and off, brake light flick on and off, brake light flick on and off (no traffic in front of them).... accelerate......... repeat.
OP glance down (if safe) at the avatar of your car on the screen. When you are braking, the brake lights on the car avatar will light up too. I am guessing you might end up surprised at how often that actually is.
