This! Living in Scandinavia all my life, clearing ice from cars (along with the constant darkness) has always been some of my least favorite things.
Using preheat really is a Godsend for us living in this kind of climates.
Yes, it is going to eat some range, but unless you can barely make it home, it is well worth it. No scraping windows, no stuck doors, the envious looks from coworkers as you jump into your car and drive away!
I don’t think the door handles will be an issue, but as previously mentioned, the windows can be a bit stuck if you don’t preheat. At least in the Model S.
do the door handles defrost? I know model s door handles can break through ice.
