This kinda goes to prove a post I made a while back where I commented on how I can apply the brakes to get regen, but the brake lights don't come on. It is a fine line that this happens, but I can slow the car w/o brake lights.

I can also slow the car with cruise on, then release the brake, and the car speeds up. That is wierd when you think it should be off, then you surge towards the car in front of you. I am never close enough to a car for there to be a problem, but it just makes you become very alert when it does happen.
