I think the post from rolando shows a little bit of ignorance on the subject at hand. Motorist do have a real problem with respect to cyclist and it's not about speed. I can ride my bike at traffic speeds (all the way up to 50 MPH) and it's not the speed, it's just the disrespect for cyclist at hand. They still must pass you, even if you are speeding at 15 MPH over the posted speed limit.
I wouldn't expect to see the same argument about a pedestrian being killed by a careless driver. Short of a pedestrian trying to commit suicide, no one blames the pedestrian who is struck by a careless driver as being his/her fault for walking in the first place. For all the safety concerns with cycling, yes it can be dangerous, but far more people are killed in cars than bicycles every month, so the safety angle is really a moot point.
The problem is just the same old tired reasons. Careless driver or driver with a grudge to fill. The only difference is, the careless driver who crashes into another car, both parties may walk away. A careless driver who hits a cyclist, pretty much a 1 sided battle.
Maybe cyclist should put an explosive charge at the rear of their bicycle to guarantee any careless motorist is killed in the explosion aftermath of the collision. Sounds extreme, but it reminds of a good saying "Put a large spike in the steering wheel pointed at the driver and see how safe everyone would drive then".
The problem is neither technical nor political. There are laws in place, your car has a gas pedal, a steering wheel and brakes. The problem is social attitudes towards cyclist. Not all cyclist are innocent of course, but no one wants to be hit by a car. To blame those that make an effort to better themselves through exercise or just to cut down on the gas bill as the problem is a sign of poor character.
