Ya know, Chris, I been thinkin on yer problem, and maybe you could hook up yer Peterbuilt to a 40' trailer, circle around and get in the left turn lane with the rush hour traffic, and about half way through the turn, stall it, then get out and open the hood and stand there with yer hands in yer hip pockets, just looking at the motor. Maybe have a little wisp of steam curling up, for effect. You could probably block the intersection from at least 3 directions for up to an hour. After all, if you have to wait on others, no reason others can't wait on you....
