Though I have heard plenty of jokes about BMW owners over the years, they are definitely not the worst offenders in my experience. I have seen the occasional a-hole swerving around in traffic in a battered, "riced" out (if you can call it rice) 3 Series, but the people who scare me the most are minivan drivers. No offense to any minivan owners here, but as a whole, the group seems to be lacking in driving ability, courtesy, and common sense. 9 times out of 10 when I get passed in a turn lane, cut off, almost run into, etc... someone in a minivan is to blame.
