As a counterpoint (in both ways) to the post below, here's not only a European cyclist behaving in such a way as to make all cyclists pay (lane splitting, riding in blind spots, weaving between cars, cutting off a car trying to turn left, violent response followed by cowardly running away), but here's also a response/comment defending this type of action attitude.
I'm not a fan of bike nazis, or obnoxious lycra warriors, but I get just as sick of those goodie-goodie cyclists that say: "I come to a complete stop at every stoplight and stop sign just like I'm supposed to. If we want to be accepted, we have to [take it up the ass without lube on a daily basis] blah-blah blah."
Listen, the whole point of riding a bicycle is because it's fun, it's healthy, and sometimes it can be faster than a car. But you're also a sitting duck in traffic. My philosophy is that you take your own risks. If/when cagers make honest mistakes (cutting you off when they're texting while driving doesn't count as an honest mistake, btw), that's part of life.
But when an asshat like that Hyundai driver start using their brute force to step on the little guy, you got every right in the world to take matters in your own hands. If the Hyundai driver wanted in to that lane so badly, he could've waited. And he wouldn't've ended up paying for it with his mirror.
No wonder segregation is so popular.
