This was one thing I really liked about driving an electric car in the winter - you can start the heater remotely through the app. Since it's an electric heater it warms up way faster than ICE. If it's plugged in, it will not even drain the battery.
I've got a petrol car now, a later model of the same line, and the designers clearly decided that there was no need for any trickery, and they could just use the heat from the engine. Big mistake! It's absolutely rubbish by comparison.
