Some people seem to be under the impression that in California, it is illegal to lanesplit. These people love to lament motorcycles lanesplitting as a cause of accidents. I don't have a more specific "some people", becuase it's precisely that. Scattered opinions, but enough of them to make the road more dangerous for folks with only two wheels beneath them.

Some people get angry when they didn't see the bike they hit, blaming the biker instead of the fact that they weren't looking closely enough to see a skinny two-wheeled silhouette because they were only looking for cars. The biker "must" have been "flying" by them for that to have happened, right? Never mind that the person in the car was probably changing lanes without signaling when this happened.

Some bikers speed and weave in and out of traffic. Some people do that in cars too. I don't appreciate that generalization about folks on sport bikes. (Not that anyone here was making that generalization, but it does seem to be a prevalent one in the world at large)
