Come to Japan (and, so I’ve heard, several European countries) where we have a temperature setting on the tap. Mine caps at 40 by default, but you can press a little button and make it hotter if desired (up to however hot your water heater puts out).
Most of these types of faucets have a regulator in them as well in the US, you have to take off the handle to set it and most people never bother to do so.
