why would anyone do this?
The other week it was minus 14.
I went out to the car, started the ignition, turned on the heated windows, heated seats, heated mirrors, and blowers – went back inside and finished my coffee.
Seems considerably nicer than faffing about with a scraper and can of toxic de-icer then shivering my arse off for the first few miles while apologising to the poor frozen engine 😀
