I didn't see his black Volvo S-something when I changed lanes and he took offense at it. Flipped me off while passing me, pulled in front of me and hit the brakes.

So be careful, as he might hold a grudge against any G8 out there. Assuming he noticed it was a G8.

Didn't you know that Volvo is acutally Swedish for douchebag? Safe travels and watch out!
