Generally around here it's regarded as an unfortunate accident, one of those things that "just happens." There's usually an investigation (don't know how thorough), and unless there's a really glaring instance of negligence, DUI or something, the driver might get a ticket or a few hours of community service. We have a lot of cyclists, but the community is still pretty wired into the idea that the roads belong to cars.
Also, Nevada's incidence of a-holes is substantially higher than the national average.
