I was once one of the people who caused this problem, until I got clobbered by an iceberg at highway speeds and understood all too clearly how dangerous it can be.
I don't have any problem with the law, if it's enforced reasonably.
Exactly. It is clear what behavior is being targeted. FReeper paranoia that this is going to cause us all to be strip searched cause we're driving home and snow is sticking to the car isn't helpful.
Another factor to consider is those days when it gets sunny and/or above freezing, and the snow packed on a car roof suddenly slides down your windshield when you stop.
