It definitely becomes rapidly intuitive. They’ve done it for 5 years with the Model S and I’ve never spoken to an owner who said they missed them. I don’t see that being a hot topic of conversation here among people who have owned the cars for a while, either.
The problem is people can adapt to anything. I think if something reaches a threshold of usability, even if in reality it's objectively terrible (I'm not saying this is), people won't complain. Nor realize that there is actually a waaay better way of doing things. This is as expected I guess - most people aren't continuously mulling UI issues on a daily basis.
