No one said anything about anything being broken, just about the ability to remotely heat up the car before starting to drive. Having a heating and having a remote controlled heating that works with the car switched off are two separate things.

Huh?

Across decades, I've heard of many cardiac events from shoveling the driveway, but absolutely zero from scraping ice off a car windshield. This correlates to the vast difference in effort required by each action — scooping, lifting and moving tons of snow, vs scraping at a few ounces of ice (which is even easier if you let the car run a few minutes with the windshield defrost on).

Now, if we had car (not trucks setup for plowing) that could automatically clear the driveway, that would be a must-have feature in areas with winter climates...

Dude if scraping ice off a windshield gives you a heart attack you have way bigger problems than your car not heating up remotely. Go see a doctor.
