I think you have to respect those guys, I mean you gotta follow the laws regardless but just as a person you should give them a bit more space because even though you might catch a fender bender occasionally if they get touched at all it could be all over.

Some guys I've seen do get a little crazy, weaving in and out of cars or cutting people off themselves so at times yeah you'll want to let them know to chill out and push up on 'em but for the most part I feel like unless you're just a bad person trying to kill a poor guy you gotta give em space....
