You’re supposed to leave one car length between yourself and the car in front of you at a stoplight. How much room did she leave between herself and me? One… FOOT. So I roll forward to make more space, as sometimes people make mistakes in gauging stopping distance. But she ROLLED FORWARD TOO to ensure she was EXACTLY one foot off of my back bumper. I watched her change lanes and do this to somebody else at the next light too. It looked like she was going to rear end them. Dangerous, unnecessary, and illegal following distance. One of these days, somebody with a manual transmission is going to roll back into her on a hill.
