I like the simplicity of Tesla's. I took one of our company 3's home yesterday. I will be getting a Y in the next couple of months and one concern I had was the screens and how bright they are in the car. I am an early morning guy and usually on the road by 4:30am so lots of country driving in the dark. The screen going into dark mode was great and because of the simplicity of the dash it was way better then my Outback, which has a big 12" screen + the cluster that only dim so much. The quietness of the car is fantastic as well, but what really wows people is the 3 I have at the moment has the accelerator boost purchased and man when you floor it that thing takes off!
I honestly think majority of those who complain about the lack of buttons in a Tesla, have only spent a short time driving it. Note that I said majority and not 100%. Teslas are not setup for you to just jump in as a first-time driver. There is a significant amount of time needed to set them up for you. This is because of how many things are customizable. Each of these get saved to your profile, which if saved to the cloud follows you to any vehicles you have access to.
Once you set these up, you never mess with them again. From AC settings, mirrors/seat/steering wheel positioning, to all the UI settings, including steering/speed settings. I have had my Teslas for years, and don't change the temperature settings, even when I get into my wife's TM3, since my cloud profile remembers my ac settings. When I have had loaners, all these customizable settings carried over.
It is much like your cell phone. Once you set things up, you rarely need to go into settings to change them, but yes, it took time over the years to get it how you like it.
The things I regularly change, like windows, hazards have physical buttons. The Highland 3 did remove both stalks, which if an owner is so inclined to add, can be done in a couple minutes with aftermarket OEM like parts (S3XY Stalks/Hansshow,...).
When it comes to radio switching inputs, if you are only switching between BT, Radio, Satellite, in other vehicles, yes, you might not need to look down, but pretty much all vehicles with lots of additional audio streaming, no amounts of buttons are going to keep your eyes on the road.
If I just got into a Tesla as a rental, or driving someone else's, I 100% would say the lack of buttons would be a problem.
