if a boot is needed, a boot is gotten. In this last case, this guy just needed his licence revoked. No turn signal, no shoulder check, no mirror check, just roll over into my lane, brakes, boot and horn, he looks in the mirror, and COMPLETES his lane change at the same rate. Then he continues into the turn lane without a signal. I went by him in my original lane, just shaking my head. I've given up on the bird, but a large expression of disappointment is usually in order... or a shook fist, and a blast if throttle.
