As a cop myself in a metropolitan area, I pay no extra attention to nice vehicles, other than the normal, “nice ride you got!” It’s the wanna be guys who are looking to race everyone even though they have nothing to race with. Those guys are the ones who create hazardous conditions on the roadways.......the same roadways my family drives on and yours. Trust me, even if a nice truck or sports car hits the throttle at a stop light, I don’t get worked up as long as they do it with some common sense in a way not to cause danger to others.
Just some FYI, sometimes there are occasions where police are on the lookout for a stolen vehicle, one that may match the physical description of the one you’re driving. In those cases, they may be following you while they run the registration plate to see if it’s the one they are looking for. If not, they will pull off or go on.
