It is purely a regulatory problem. FSD is not available in Europe due to the slow pace of regulatory approval.

For instance UNECE regulation 79 prevents FSD from using its full capacity to turn the steering wheel.

It's a rat's nest of red tape.

How do EU regulations prevent my car from recognizing speed limit signs?

The real problem is that Tesla sold this in Europe, but never put the slightest effort towards actually developing the localized ML model that could make it work. (Of course the hardware sucks too, but they could have done a much better job with it.)

The reason is because mobileye patented (US20080137908A1) it and won't let tesla use it.
