I was at a toll booth paying for tow. All of a sudden the car accelerated forward by itself, ramming into the toll bar. At that time, my arm was still sticking out the window while interacting with the toll terminal. This incident is something that needs to be looked at. It certainly looks like this is a result of the accident avoidance feature. Not sure why it activated either. But I am 99.9% sure that I did not accidentally press the gas pedal because I had to slam on the brakes to stop. Currently contacting Tesla to see if they can get the log to prove whether I accidentally press the pedal or not. In addition to this, there were reports of inverter spikes causing acceleration issues. Please look into the linkage of these incidents. As an electrical engineer myself, this is very alarming.
