The difference is that the heat is going the moment I get in my car. Not as efficient (and, to be fair, my experience is a bit dated here [~15 years]), but I don't have to freeze my butt off for 10 mins waiting.
This is ridiculous, I have never had a car need ten minutes of driving to make heat, even in a Pittsburgh winter. I have had a driving license for 36 years.
I drove a Renault Zoe around Stockholm in the middle of winter. Great car, except for the heating... takes a long time for it's little heat pump to warm up.
Is that an all electric car? Petrol combustion gives off a lot of heat, but if the thermostat is stuck open this works against the goal - modern vehicles will set a fault in this case because slow warm up causes more fuel to be burned and emissions to be expelled.
