I was driving on the highway 12/04/2014 with cruise control active going about 75 mph. a truck in front of me became too close because he was going slower. my car began accelerating and i hit the brake to slow down, and de-activate the cruise control. however nothing happened and my mini-cooper continued to accelerate and i hit the rear end of the truck. i used the cruise control on/off and turned off the cruise control and i stopped accelerating. i changed lanes to pull over, however i had no brakes. i exited the highway as there was a big hill, however with no brakes i went flying through an intersection while honking my horn, and through the red light. the only option was back on the highway after the light and i eventually slowed down and then used the emergency brake to stop. i really panicked and thought i was going to die. the truck had no damage, however the mini-cooper got a dent on the hood. this also happened briefly about a month ago, where i hit the brake and my mini continued to accelerate while in cruise control, however when i turned off the cruise control that time, the brakes were fine and i had a close miss of rear ending another car. in hindsight i should have put my 6 speed in neutral or turned off the car. at the time, these options didn't come to me in a panicked state. *tr
