Yep, I think the cop had been chasing the bike. When the dash cam car heard the sirens he pulled over, and probably the chasing cop was called off at that very moment for the sake of safety. Evidently, that was a good call.I hear sirens at the beginning. I think that minivan that passes is a cop and the car was pulling over because of the siren/lights. The right lane goes to 400N - rider was probably already being pursued and was headed there to get away... Was the 2nd rider that passes-by at the end an associate?
