Interesting video, whilst I see the removal of the indicator stalk to be a massive own goal, I think it's possible it could be adapted to for driving in normal conditions when not turning the wheel? Seeing as your hands are on the wheel already... Roundabouts are a another issue though...
What I actually think is far worse, and you can spot this at around 5m25s in the video, is having to look at the screen to stop / select gear. This is something I just naturally do with 22 RW Model 3. I don't have to look anywhere and it's been far more convenient than a gear selector. Car parking and 3 point turns are a doddle. I hate having to look at the screen to do functions at the best of times. If the wipers randomly go off on Auto and I have to switch it off on the screen while driving - I find it really distracting. Of course on a test drive I will be able to get a better understanding, but it seems to me to be a really unnecessary concession removing the stalks. That rear screen would be a total waste on me, as it would never get used. I'd resent it more for draining the battery!
The LED lights and the better suspension are a big bonus though...
