1. How about those stupid macho wannabee pricks who park their big trucks perpendicular to the sidewalk, with their two front wheels touching the curb and the rest of their vehicle sticking out in the middle of a cul-de-sac. That way, the rest of us have a wonderful time trying to turn around or park. Ever heard of a driveway or a garage?
