Doesn't change that it isn't accurate.

In Scandinavia, lack of air condition in homes vs. presence in cars has nothing to do with carbon programs.

What options become standard in cars, and what options are cheap to implement in cars (adding a bit more piping during assembly), follow an entirely different market dynamic than the retrofitting homes (most houses are either pre-WW2 or from a boom in the 50's to 70's) with air conditioning to handle what used to be very short bursts of heat.

Not only did weather not demand it, old brick houses have significant thermal mass and during sudden heat waves you'll often find the inside to already be noticably cooler.

It's being considered now both because weather got weird and our construction went so far in energy efficiency that while new construction barely require any energy to heat in the depths of winter, they become literal ovens in peak of summer.
