I have a feeling that part of the appeal of the touchscreen for Tesla was early on, they were desperate to ship things that had problems which hadn't quite been resolved yet. The automatic downloads enabled them to sell the car with "don't worry, that will be fixed soon and will download automatically".

I guess it is clever in some regards but like others, the touchscreen on my Skoda (thankfully mainly for media) is impossible to use without taking your eyes off the road, which is truly dangerous if you need it for basics.
