I believe so. I think one issue with the UI may be the expectations of some who are attracted to buying a Tesla. There's a bit of a dichotomy with the aims of Tesla as a car producer, I think. They are heavily focussed on making all cars they produce capable of fully autonomous driving, which is a good objective. However, they are also heavily focussed on producing cars with very high performance.
When looking at the target market for any car, I think there's a fair chance that those who are attracted to a Tesla because of the performance, may well have come from a background of owning and driving performance cars, so manually driving a car to make the most of that performance is a key requirement. Making the UI less focussed on the driver, and more focussed on autonomous driving, perhaps isn't going to go down well with them.
That then begs the question as to quite why the performance of Tesla cars is designed to be so high. Fully autonomous driving doesn't really need anything like the performance even the SR+ can deliver, given that it will be designed to behave as if the car was being driven by a "perfect driver".
I can't help thinking that those that may be attracted to the idea of never having to drive their car perhaps don't have a lot in common with those that want a performance car that they can be completely in control of.
