It is beyond my understanding how or why anyone would attempt to drive a vehicle that is not properly cleaned off. Cleaning off a little peep through spot on your windshield and on your back window is soooooo not safe - BLIND SPOTS! Then there are those who don't take the time to clean off their headlights or taillights. How are other drivers supposed to see you when its snowing or whiteout conditions? ACCIDENTS waiting to happen! Please not just for your own safety, but for other drivers out on the roadways, CLEAN OFF YOUR VEHICLES PLEASE! It is the law! Also, just as a side note, especially to new drivers on the roads, DO NOT engage cruise control when the roadways are wet, even if its just a light misting of rain, you can lose control of your vehicle very quickly.
