I did get it with the full self driving. It was a tough decision because it was so expensive but I think the right one, as it's just gone up by £1000 today and it'll just go up and up.
The frustration is with UN/ECE regulations. The car CAN enter a motorway, drive along it, changes lanes when necessary and exit it without driver input. Do to regulations, however in the EU and UK it can only suggest entry/exit and lane changes, you yourself have to indicate and tap the wheel to change lanes. Also, not sure of this is EU as well but certainly UK, in the rest of the world it'll pick a lane change, indicate then sit in it's current lane until the next lan is free. In the UK if it can't change lanes in 5 seconds it just cancels. Also the UN/ECE regulations limit the amount of stirring lock that can be automatically applied, meaning if the bend is too sharp the car can't do it.
ALSO smart summon (where you can get the car to drive towards you on it's own) works over wifi in the rest of the world and in America has a 200 ft range. In the EU and UK it has a maximum range of 20m. Worse than that it only works over Bluetooth and therefore you have to be standing next to the car, making it pointless.
Maybe I should have voted Brexit to get rid of these rules?
