Heated screen is one of the top requirements for a car.

I just pour a few litres of fairly cool water over the car, only takes a
few seconds and works on all windows and door mirrors, not just front
and rear.

That would frequently just cover the car in ice and/or create an ice
rink around the car... Aerosol deicer on the side windows struggles
or even freezes at times. Start the car, press the auto defrost
button. Wander round clearing the side windows, lights etc. By the
time those have been done the screen is either clear or the wipers
can just push it off.
