I had just left my doctor's office and gone to a parking structure where I had parked my car for the visit. I paid the parking charge, got back my validated ticket, and inserted the ticket in the gate-arm machine. The gate lifted, and I put my foot lightly on the accelerator to exit from the parking structure into the street. The car then picked up speed, well past what it should have picked up based on the light pressure I had put on the accelerator, and the brakes had no effect. The car went faster and faster, crossed a street, and crashed into a concrete wall. On impact, the airbags were deployed. I suffered serious back pain, and my wife was in the hospital for three nights with two broken ribs. The car was totaled.
