This is good question I've asked myself often. So far I've never done it though.
I had an incident this morning on back roads where a big ole 4x4 jacked up diesel truck pulled out in front of me while I was doing around 50 mph. There was no on coming traffic, so I passed his ass. As I was trying to make the pass he tried to block the other lane a bit. What a dick head. Anyhow, once on the main road (double lanes) he comes flying passed me like a cool guy. I had my EPAUTOS.COM magnet on the back of the car, so hopefully he stops by here to say hi.
