In Europe, most of the Tesla features are disabled because they were deemed hazardous. Only lane assist and adaptive cruise control is enabled. The others are severely limited or disabled (Summon etc.)
Do you have a source for this? Cause it seems to me that they could easily deliver something like summon, seeing as parking-assist/automatic-parking already exists.
When it comes to safety though, I disagree. One of the decent things to come out is the Euro NCAP rating. The manufacturers are not part of the testing process, apart from they need to supply cars. Each car is then given a rating.
For Autonomous driving, from what I can see its still down to individual states.
