Its not worth the risk. One pursuit I was a part of, there were 2 people on a bike evading (passenger was wanted for Assault 1st degree, which in my state is attempted murder) so we had to chase as it was a serious offense, the biker hit the roundabout and flew dozens of feet in the air. The driver passed and the passenger got seriously injured. If they are just cop baiting IRL (happens more than you think with bikers) then its not worth putting people in danger especially when you have a guy weaving in-and-out of traffic just to mess around. Mainly referring to sports bikes like described above though.
