>I mean you can try, but they're going to take off. Unlike a vehicle, they're just going to dodge between cars and run up embankments.

This. ^^^^ If the cops try to pursue, and the bike/ATV takes off, they might cause exactly the kind of accident we're seeing in the OP here. I mean, they blast through red lights and stop signs when the police AREN'T chasing them. Imagine what they'll do if they think the cops are about to impound their bike?

I have seen the swarms in my neighborhood a few times. It's a miracle that we don't see this kind of headline more often. The bike and ATV riders drive like crazy people who think the laws of physics don't exist.

I actually don't think many people would care one way or the other about the bikes if they weren't doing all kinds of stupid things in the middle of oncoming traffic. Ride bikes? Fine. Share the road? Fine. Pop wheelies in the middle of the freaking street with cars right behind you? NOT fine. Cut in front of oncoming cars with inches to spare? VERY not fine.

They responded to skateboarders' needs by creating a skateboarder-designed skate park in South Philly. Maybe the next thing they should build is a track where these dirt bikes and ATVs can do all the tricks they want, without causing traffic accidents.

They can confiscate them, which is good, but they are discouraged from chasing them down. They don't want the bike/ATV rider to cause an accident while fleeing from the police.

I find it sadly ironic that some of the areas around Philly, where some residents were mocking our issues with these hordes of dirt bikes and ATVs swarming around, are now dealing with swarms of their own. It's not just in the city anymore.
