My guess is that Tesla is not taking any chances with a newly trained NN. In the US, they've taught the car what every feature of a parking lot looks like. In other countries, parking lot objects could look very different.
My guess is Europe has decided to cripple Tesla to allow other car makers to catch up:
- too low speeds in bends
- no automatic lane change
- no smartsummon beyond 5 meters
Tesla should not sell FSD in Europe, it won’t be able to deliver.
