While out doing some running this morning I was passed by a car that had every window except the windshield covered with snow. The rear window was completely covered, there is no possible way the driver could see anything out of it. The door windows were covered by snow that was starting to melt from the heat inside the car, so I'm sure they could see something but visibility was definitely less than 100%. Snow was on the front of the car as well, covering most of the headlights. The best part is this driver went right by not one but 2 leos who did nothing. I would say it was unbelievable but for the fact that I wasn't surprised.
