Limited experience with police so far in my 7 but I did get pulled over twice in one night within 3 miles.
Mind you at any point in time, my 7 is in violation of at least (inspection, exhaust, no front plate, no rear plate light) at any point in time.
Got pulled over for no lights on the rear plate. Told the cop cars like this come with certain limitations. He sympathised and wrote me for failing to notify dmv of change of address (was also true). Then when pulled over down the road they said they saw me take a turn a little too fast and were curious as to what car it was (during the night). Chatted for a bit and off I went.
