The woman in the vehicle was attempting to park in a space too small between my car and another vehicle. She almost hit my car many times coming inches from my rear bumper. Concerned she would hit my car I attempted to get out of my parking space, but she blocked me in with only about 6 inches to spare. I asked her to back up so I could get out, but she refused. I was blocked in not being able to get out of my parking space. Later, it took me creeping 3 or 4 inches and 20 minutes later to try to get out.
