You should read up the full court testimony on the Emma Czornobaj case. While she did do something really stupid, the bike rider also did not stop until he tried to wave at her first, then the used the rear brake and "layed 'er down".
If that were any other obstacle in the road, it would have had a very similar outcome.
It's very cultural to think that "cagers" are the problem, but 3/4 of fatal crashes are some fault of the rider, and an even larger number of non-injury crashes are 100% rider (those never get reported.)
Riders need to understand this before posting ranting videos on YouTube.
Emma Czornobaj is back on the road.
