You use GPS to get an incremental distance traveled, and cross reference it with a number of rotations of the wheel (simple optical sensor, like abs wheel). You’d need a few algorithms to adjust for things like tire temp, tire pressure, and also extract meaningful data from the GPS plot in order to get a more accurate distance per wheel, because of turns. If you went 100 miles turning left the entire time, the right tires travel further than the car’s COG, which travels further than the left wheel.

But it could be done.

No you are right your idea would definitely be better, for some reason I just assumed GPS would be terribly inaccurate.
