the front license plate thing, I particularly dislike. In my teens I drove a firebird, the front ends come to kind of a point, they are not flat on the front like most cars so affixing a license plate not only looks hideous but there isn't even a good stable place to put them. So at my friends suggestion I put my front license plate on the front air dam. It was still fully visible from the front, but apparently there is some minimum number of inches high it must be sitting because I got pulled over for it all the time, and the only time in my life I got in any more trouble than a speeding ticket, it all started because of that damn front license plate getting me pulled over. these days I don't worry about it because my truck has one up front and it looks fine.

I believe the police like to aim their radars or lasers at the front license plate to gauge the speed of an oncoming car because it provides a nice flat reflective surface
