I had an automatic 2000 Chevy Cavalier that I drove lightly around my second home when I visited it every few weeks. About 2 years in I came to red light and, in applying the brake, it fought as though I was stomping on the gas pedal. I regularly drive stick so I popped it in neutral as I brought it to the side of the road and the engine kept revving despite neither of my feet being on any pedal.
I turned off the car and re-started it without any problems so I took it to my mechanic down the street and had a friend pick me up. The mechanic gave a full run-through and basically didn't believe me.
I drove the car around for another few months without incident until I was taking a longer drive at night on I-95. The car started unexpectedly accelerating so I removed both feet from the pedals and it kept speeding up.
Long story short, this happened several more times (I have low risk-aversion) despite having the electrical system replaced and having numerous mechanics that I know and trust look at it. Before I just gave up on it (annoyed - I like to know what is wrong) one of my mechanics took it out for a drive just to try it out and had it got away from him as well. We never did figure out what caused it.
