Replacing an ev motor sounds easier to me than an engine. Assuming you can get parts

But do you have the equipment to calibrate the resolver of this new motor by connecting to the inverter and writing the new resolver offset into its EEPROM? I thought not.
If you swapped out the motor on your EV like you suggested, it would start spewing out illegal levels of EM interference, screaming like a pig and randomly chopping out at high speed.
This is why self right to repair is a complex issue. Even for EVs which seem simple but are not. Every single component is so tightly coupled.

Sounds like a simple Python script you could download from an enthusiast forum.

Or a calibration mode where you roll the car down a small hill for a couple of revolutions.
Either way still sounds easier than replacing the engine on a new car where you have to do some software module stuff to get the engine talking to the cars computer.

It seems about on par with performance tuning an ICE ECU which is done by hobbyists all the time with a laptop running any of a number of readily available software packages and an ODB2 dongle.
I’d also suggest that you are operating under the illusion of self-repair. Is replacing a transmission something you can do? An engine? Sure let’s say you can. Personally I can’t replace an engine any more than I can replace a motor on an EV. I don’t have the tools, I still have to rely on society to procure the engine and tools and ship them to my house, etc. idk why this would be more or less difficult than replacing something on an EV besides the battery pack.
I don’t really follow your EV battery comment unless you live in a very abnormal situation which is ok, but it makes your comment much more akin to an abnormal anecdote than a generalized point regarding EVs.
