Driving in DC Traffic

Let'sme just say...I HATE driving from Quantico, VA to Bethesda, MD. That really is my only complaint about living in this area...is that for any specialty appts you have to drive all the way thru DC to get there...I nearly got sideswiped TWICE today. HELLO?!?!?! That's what BLINKERS are for!!! USE THEM!!! Seriously...traffic doesn't normally bother me...but when ppl act like complete idiots and try to run me off the road...I take offense. >:(
