Have not got door from passenger or driver side that resulted in collision yet, but came close couple of time. Most were from passenger in the back seat. Not their car and they would care less regardless of bike or cars is approaching. I did get some close call like this riding in the city (San Francisco) Too many one way street where passenger jump out of the left side of the street from the left side of the car while I am on the left lane ready to do a left turn on a one way street into another one way street.

I have once got some garbage thrown out the driver side window of a parked car at me. I think it was Burger King wrapper. The driver didn't look or anything. Just simple toss it out. It was only several feet in front of me and I lean left almost going into traffic. Next time I rather eat the left over garbage than playing dodge ball with cars.
