You go down an alley as someone pulls in. Who backs up? Normally, if you can't figure out how to pass each other, the driver closest to the entrance would back up. Well not in this video. These two can't really figure out how to handle this very complicated situation and the driver of the BMW takes the flight response by simply getting out, locking the doors and taking off. That'll teach him.
Enjoy and don't try this at home, just back up.
