Shane Farthing of WABA has a good long essay on the messed up standard by which cyclists in DC must operate in order to seek relief from insurance companies and the courts. In it he has a denial letter to Evan Wilder, who many may remember was passed too closely by a driver who then slammed on his brakes resulting in Wilder hitting the truck from behind. In it they say that he contributed to the crash by failing to keep a careful look-out. Here's the video for thos who are unaware. The whole thing is a good read.
