You've obviously never driven around the Washington D.C. area. "Too close" around D.C. is all the room you'll ever have for much of the day.
C.M. may not have had the pleasure of driving in the District, but I have. It is truly insane... but then so is L.A., Chicago, Atlanta, etc. Your comment takes the topic off on the "overly-aggressive driving" tangent. I see people deliberately accelerate to block out cars that are trying to merge in front of them - happens all the time. Give me SUVs over those a-hole drivers any day of the week.
