I completely agree. In this case, there are at least four groups: automobile driver, motorcyclist, bicyclist, and pedestrian. We are nearly all biased, but when we exchange roles, I'd argue that most of us (including myself) will point the finger at the other group because it's so much easier to see the faulty behavior from an outsider perspective.

That's human nature, and it's exactly what's happening in politics at large. People from cities don't understand people from rural areas and vice versa. We think we're all so far apart, but in reality, our views are all grouped really close together (they're all human views). This is why we face major challenges solving larger problems, like global warming or plastic in the ocean, because it's easier to counter-attack than to do the work to change our own behaviors despite the faults we see around us.
