I was parallel parking and when I put the car in reverse and barely touched the gas it suddenly accelerated into the car behind me. It was so fast it shot backwards like a rock into the car parked behind me. This was not driver error. It is now with an independent mechanic so I do not know at this point if they can reproduce the incident. I did not take it to Honda as I wanted an independent an unbiased report on the car. No warning lights, etc. before hand. The car behind me had somebody sitting in it and he hurt his hand. BUT if there had not been a car parked behind me I would have shot out backwards into a very busy street. Or had somebody been walking behind the car the would have been killed. The body damage to both cars shows that the speed had to be high at impact, and given the small space between cars when one is parallel parking I would have had to put the "pedal to the metal" to cause the kind of damage that was sustained.
