I’m practicing for my driving licence and I’m going to driving school, just out of curiosity though I’ve looking on YouTube how to start and run a car and I’ve seen at least 3 different methods, I dunno which one is the correct. Things like the order when you release a pedal or when you need to press the clutch keep switching…
The outside is the easy part (unless there is thick ice): use the water spray with the wipers. In the winter, the water contains a thawing solvent.
For the inside, what I personally do in the winter: before parking my car in the evening, I open all the windows for a few minutes to let the cold air in (also switch off the heating). Cold air is very dry. So it does not mist up (most times) in the morning.
