I think it's the luck of the draw. I too like the clean look of no front plate, but I was pulled over for no front plate a few years back. I was waiting to take a left turn at the light and the cop saw me from across the street, waited for me to make the turn, got behind me, and pulled me over. While he was writing the ticket, there must have been 30+ cars that passed with no front plate. This was in Irvine, CA by the way, where there are PLENTY of cars without a front plate.
I've since installed front plates on both our Y and X just so I don't need to go through that hassle again. Plus like others said, it helps avoid a reason to pull you over. We have tint (including the front windshield) on both cars and would hate to be pulled over for no front plate, then get cited for tint too
