Assuming you can get the car to start (mine needs an engine warmer at that temperature), it takes at least 15 minutes of driving to reach that temperature. Unless you’re going on a longer trip the engine most likely wont be warm by the time you reach your destination.

I had to drive in -30C once, the engine could not get up to final temperature after 2 hours of highway driving because I had to run cabin heater at full blast on windshield and side windows so they didn't cover with fog inside. But that was in very old low power car.

My tiny diesel car (2008 Toyota) needs its auxiliary heater below around -15 C for highway trips. It's a switch in my dash that burns extra fuel, otherwise the engine won't get up to or stay at temperate.

Pretty normal with diesel as it gives off less heat than petrol. I have a van with an 88kW engine, and even at -5c I can see the coolant temperature drop when I am idling down hill and have the heater on. Any colder and it's worth blocking the radiator with cardboard.

Protip for next time, cover the rad halfway with some cardboard and this will help a bit.

Garages exist though.

Schrodingers garage. Ceases to exists when talking about EV charging but exists when ICE vehicles need cold starts.

Heated ones are rarer.

I once had a condo with parking in a cave that was above freezing even when outside was -30 C (or F, close enough at that part of the scale). It was a great winter perk.
