Tesla could do better as a software UI company .. overall the total software stack is pretty stable, considering the amount of stuff that is handled by the cars computers .. it's the UI that needs work. And have you ever looked at the competition??? Not saying two wrongs make a right, but I'd take V11 interface over the offerings from Ford, BMW, GM etc any day.The issue is that Tesla sucks as a software company. This is more of a garage startup behavior.
That said, V11 is clearly the work of a UI team focused on "making it look nice" versus "making it functional AND clean". UI designers, apart from the very talented ones (rare), tend to confuse "different" with "better". They desperately need usability oversight. Given that their main UI design guy left just after V11, I would guess there has been some significant shakeup after the V11 feedback.
