It gets way easier for “feel” of weather too! In most habitable places in the world, 0°C is around as cold as you’ll regularly see (also a handy number for when you need to watch for ice). Similarly, 40°C is around as high as most habitable places get, also a nice easy number to work with.

In fahrenheit, these numbers are 30 and 105, I mean I can get rounding down for ease of use but you’re moving the reference points a lot to make it 25 to 100 for what you usually see and that’s certainly not more intuitive than 0-40

What manual Mercedes is for sale in the USA? I’ve never seen one, that could be a whole lot of fun!

Taxes are super high. I’d be big mad if I was Californian, they get very little investment back from federal taxes (they are effectively subsidizing the poorly run states) and have to make up the shortfall at the state level.
