Most cops let you decide whether or not you'll get a ticket.
If you're a ****** to them - ticket.
If your violation was blatant and dangerous - ticket.
If they had to follow you forever before you stop - ticket.
Immediately and safely maneuver your vehicle to the right, off the road enough so the cop doesn't get run over, roll down your front windows, turn down your radio, don't BS him and be polite? - Probably a warning.
