Just one, and it was as a driver. In 1968 I was driving to Hackensack, NJ, when another car went speeding through a red light, smashed into the left rear fender of my car, and drove off without stopping. I reported the hit-and-run to the police, but the other driver was never prosecuted. My insurance company did win a lawsuit against his insurance company for the damages to my car. I gave a deposition by telephone and the case never went to trial.
Same question, how many car accidents have you been involved in (even as a passenger)?
