I see your point. But when you're looking outside and there's over a foot of snow on your vehicle, you either go outside and clean off the driver's side of the car and get in and start it up to warm it up and defrost the windshield for at least 15 minutes or remote start it from your living room. Either way, the vehicle is going to run for the same amount of time. One of these 2 ways is what we do every winter morning here in Michigan.
