Personally, I like to back into immovable objects. Well, sometimes they move. I have backed into light poles, fences and a brick driveway lamp-holder (which cost us $300). The owner said, "What I don't understand is that we have a circular driveway. She didn't have to back up."
I also used to leave my car in gear and get out of it and it would merrily roll down our driveway, luckily not killing anyone. I did scrape the entire left side of a beautiful car the first day I had my license. (age 17) I think that covers all of it.
Have I scared other drivers? I'm sure I have, especially when I was on a freeway in Las Vegas that was undergoing construction. It was night and all of a sudden my lane disappeared. I think I scared the guy next to me when I sidled over to his lane as I didn't have one any more.
My husband has only hit one other car. He was stopped at a red light. The light turned green. The lady in front of him took off and then stopped short in the middle of the intersection. He rear-ended her. The cop said it was his fault. If you rear-end someone it is always your fault here.
Once, someone in my family, who shall remain nameless (she knows who she is) drove over the sidewalk into a field when I told her to turn left. It is located beside the Motel 6 in Missoula, Montana. I said, "I meant turn left into the driveway."
