gnu, another fun tip...

When someone passes you at night and cuts you off, follow them just a little to the left, off-center. Your headlights in their side mirror can be irritating. I learned this when commuting. Of course you can always act real dumb (easy for me) if the person has road rage and tries to come after you.

I also learned while commuting in the "East End" of a big city vs. the "West End." The BMW's are the rudest drivers. Those junkers with no tail lights are ususally more polite.
