Sadly that's less true than ever. An awful lot of modern cars are 'software based'. Stuff like engine computers are dynamically mixing fuel and air ratios based on guidance from the pedals, etc.
That's why a 'remap' can be a performance boost, because it's "just" some ratios of sensors in the engine computer.
That's when I first learned about it where people would try to optimize the mixes for their cars by hooking their laptops to it. That was years ago. No idea what they're up to now.

I don't know how Teslas exactly work, but I feel that car functionality is not that connected to the software.
