Looked now at the registration data from Norway, Germany, Switzerland and Austria - all of them up nicely in September and YoY. Thats may be different for some countries but obviously numbers are not driven by a few outliners like Norway only but across the board.
Don't see a reason why that demand and production increase should not continue throughout Q4 moving into 2018. Expected 100 k units this year look to me therefore increasingly likely or conservative.
My assumption: with every Tesla on the road the "neighbor envy" factor is kicking in and we will see continuous growth after the early adopters did get the car already. So it gets more and more mainstream as all doubts raised before has been proven not to hold e.g. Range Issues, Missing Loading infrastructure, Batterie deggresion, Costs ..... you name it
My prediction: S&X deliveries in 2018 are likely 120 k to 150 k.
