With temperatures below zero it's always difficult to get going even if the engine itself starts without hiccups and I'd like to know what to do better so that I don't need to wait ten minutes before the car is somewhat safe to drive.
It takes ten to fifteen minutes before the car is driveable in winter. I follow my father's routine of starting the car, opening front doors or windows at least a bit, cranking up the air blower to full power for windshield (with AC on), than get out and scrape off ice from windshield and windows.
After this, it takes about ten to fifteen minutes, before I can drive safely - actually see through the windscreen and windows. It seems as though a new thin layer of ice forms on my windshield and without the blower set to full, condensation from my breath forms ice buildup on the inside as well. Having front windows open helps a bit the icing problem at the price of freezing me some more. The problem is made wors when there is any light source directed at the windshield (sun, street lamps, other cars), because otherwise transparent winshield becomes somewhat opaque. Applying windshield washer is no option, since the liquid available here is non-freeze for storage only and freezes as soon as it hits the frozen glass.
Other problems are that the user manual of the car strongly advises to get going right after starting the engine (as opposed to leaving the car to heat up, as was usual in the olden days), and I hear that local laws actually forbit leaving a car idling (you don't get actually fined, but I don't want to set ground for neigborhood complaints).
Usual temperature in my location doesn't fall below -10 °C, I have a 10 year old diesel car without dedicated electrical windshield heater or electrical air heater (only engine coolant heating).
Is there something I can do to shorten the time needed to get the car to safe-to-drive state?
