It's good it works for you. But it certainly does matter, and no, it doesn't always work. Like with anything on the internet, though: my experience vs your experience.
Never got in the car having one layer too many and having to turn down the temp? Or the other way around: not enough layers on and realise 10 minutes into the drive that it’s a bit chilly? Is your preferred temperature the same as the one of you passenger? Or you get in the car from a massive rain and you need to blast that aircon and bump the temp to deal with humidity completely obstructing the windshield?
If your car has crappy thermostat control, then how does that universally apply to other cars?
My thermostat just works. I don’t live in an extreme climate, so layering isn’t a thing. The car has a button specifically for defogging your windshield, so that is treated separately from climate control. You can hit max if you want drastic temperature change, but it’s a heat pump so thermostat is the only way to go really.

See, you don’t. It’s okay.
“It barely ever rains in California. I don’t understand why we need wipers. And when it rains once in 10 years, I can stop… I don’t understand why everyone cannot just stop. Why do we spend money on those little engines and wipers.”
