some cyclists are overly self righteous and are going exert their "rights at all costs.  they have  legal right to be on the road and it'd just something you deal with. sometimes you gotta yield.  
  I'D like to throttle people who do 10 or 15 miles under the limit . i would downright draw and quarter someone who's going to make all the cars behind them on an entrance ramp merge onto beltline, for instance, at 45 miles per hour. i go nuts anymore when i drive. i'm a very safe and outwardly polite, but inside the car  - OMG, I am cussing, making suggestions, yelling at them... the other drivers  aren't aware- i control  myself,,,or filter it way down, when i have passengers.
