Specifically, the post I was replying to was lamenting a future where EVs all try to be like Tesla, putting nearly 100% of the instrumentation and controls into a single large touchscreen.

This is unique to Tesla, AFAIK. It worked out very well, it is a brilliant cost-saving measure that can also be marketed as 'elegant'. Have to hand it to Musk on that one. The R&D required to build a normal car interior is expensive, so skipping most of it was a phenomenal move.

So anyway, my point is that there are lots of non-Tesla EV choices, and by-and-large almost all of them are just normal cars with normal dashboards and normal controls, just with electric power instead of gasoline. A few manufacturers seem to be trying to ape Tesla's design on their EVs, but personally I expect a reversion to the mean. Too many people could care less about driving a touchscreen.
