I think the "single ipad" thing in Teslas just makes them cheaper to build. (The other reason local Liberals are trying to get rid of their Teslas -- they are now too cheap and are no longer status symbols!).... I actually find the "big single screen" to be pretty nice, because the mapping is so good. It's just the 2022+ telas which require you to do "Forward/Reverse" switching on the screens... pretty bad...
The other thing -- the autopilot on Teslas is VERY VERY GOOD. I can easily go across LA -- fifteen miles -- on city streets, with lots of complex traffic behavior and impatient, fast drivers, and the autopilot is a MUCH safer driver than ANY human including myself.
