I agree biking like that is totally out of line and gives cyclists a bad name and pisses off motorists and makes them hate us even more and more hostile towards us...

But I will say, and not to sound like some kind of hard ass, but part of why I enjoy riding my bicycle is the thrill factor. When you're hauling ass down the bike lane, next to a fully loaded 18-wheeler or beer truck, and knowing that at any moment one of the cars on your right may open their door and whale on you, possibly sending you under the wheels of that big rig on your left... and maybe you don't have a helmet on and maybe you don't have brakes... and maybe your testicles are in your throat as you decide to take the center line instead of the bike lane because of some double parked cars or delivery trucks... and you're giddy with the freedom and risk and speed involved...

I get it. And I love those feelings, that rush you get from cycling in the city that you just don't get from a country road. But yeah you still can't be screwing around like that where you are relying on cars not to hit you as you purposely ride in their way, etc etc. Whole lotta disrespect there. For them, for yourself, for the cycling community. Just very uncool. And the fact that they get to make movies about it is infuriating. They should just get the names of those dip****s and write them all a buttload of citations. They shouldn't be allowed to profit from that, and as Scrod said, it very likely convinces kids that they should be out learning to bike that way if they want to be "cool". And many will surely die in the process. And many motorists will have to live with the fact that they injured/killed a kid on a bike, even though it may have been the biker's fault. So much wrong with that situation.
