Ok, so today I got the Traffic Stop Backup call, I was on Ocean FWY and the call brought me all the way to Route 13 in Sandy.
When I got there, the cop is sitting in his car with no lights on (i know that's to avoid sirens being on due to ELS, but if the cop would spawn outside the car, the lights could be on on arrival.)
I get out, he gets out and then... nothing. Can't talk to the cop, can't talk to the ped in front. I got a few notifications about the ped's plate, but am I missing something?
