Yes; I had a car turn left into a driveway right in front of me. No signals, nothing. Just all of a sudden they were headed across my lane. I grabbed the brakes and tried to go behind them, but I was too close and slammed the passenger door pretty hard with my handlebars and shoulder. I wasn't hurt, and neither was the bike (aside from having to straighten the bars), but I left a big dent and gouge (from the brake lever) in the passenger door of the car. The driver looked like she s**t her pants, though.
