It's true though.I know a guy,we were in Denver at a truck stop.Went next door to the motel bar,had a few(or so)shot some pool,went back to our trucks.Mine was already running(back when you were aloud to idle for heat/cool)He jumped in started his and cops drug him out and arrested him(in the truck stop)Neither one of us had loads,so we weren't going anywhere,anytime soon.
Afterwards we were told,that it was a common practice for that truckstop.
And yes we were VERY legally drunk.
