A tombstone doesn't differentiate ROW. Motorists are known for being A-holes to bikes regardless of traffic laws, it's unfortunately something we have to deal with so...
I am actually convinced that it is the motorists' attitude towards cyclists that make most avid cyclists such A-holes to everyone else. How many times has a car pulled in front of you while not looking or not caring and you follow that action with some verbal assault on the motorist? If you live in a big city I promise it happens 1-10 times each ride. Well as they say "practice makes perfect" and eventually you turn into a permanent A-hole yourself!
