“I was calmly driving slower than 35 MPH on a city street when the car suddenly slowed down and stopped responding to the accelerator pedal. When I tried to step on the gas I heard a big explosion-like sound. Then all of a sudden the car accelerated to what seems like over 100 MPH and the breaks did not work despite me pressing the breaks several times. I shot into 3 cars ahead of me that were at the red light. The other cars received substantial damage; I saw that others were injured. My car was completely damaged/crushed in the front and a fire had broken out. …”
