So here's something weird - a huge group of freestyle stunt bikers led police on a crazy chase through the streets, even bringing in helicopters and additional units along for the ride. A few didn't get away, but lots and lots were able to outflank the cops, like something out of GTA Online (if the cops were less homicidal, that is).

From the uploader's description:
