I don't think we should hang him, possibly we could just throw him under the wheels of a passing bus.
Part of the problem is that most automobile drivers don't know or in some cases even care about the consequences of their actions.
"Gee officer, I just didn't see him". He was only wearing a bright yellow jersey, with flashing strobe lights on the bike.
"I didn't realize" is not an acceptable response. People die from this sort of inattention.
Most of my experience with this sort of idiocy comes from over 20 years spent on a motorcycle (rather than a bicycle). More than one of my friends has been killed by drivers who just didn't see, know, or care.
