Not true. I was driving on I-20 through Dallas after a rare snow/ice storm a few years ago and one of those 50 lb frozen frisbees sailed off a car well ahead of me and landed on my roof. Fortunately it didn't hit my windshield. This is an objective hazard...fortunately we don't have to deal with it here as much as they do in snow country. People should lay off the kneejerk responses and analyze whether a law is actually necessary. This one doesn't interfere with anyone's life, liberty, or pursuit of happiness, doesn't infringe on anyone's freedome in any material way, and does make the highways safer.
You exagerate. A 50 pound block of ice would be about 1 ft thick, 2 ft. by 3 ft. and it would be solid ice not the crackly, crumbly stuff normally on cars.
Actually, it gives the revenooers just one more reason to stop you and collect "revenue". Is the offense an objective measure? What if you're driving in a white-out? Do you have to stop and risk an accident to clean your vehicle off?
I've driven in some REAL s**t, let me tell you...
