I went for a few years renting higher end cars on a regular basis. The primary functions on every single one of the “modern cars” were easy to figure out with the exception of the Teslas. For occasional use Tesla’s controls are absurdly cumbersome verging on dangerous.
I can understand your experience would be different if it’s your primary ride.
I can of course only speak for myself and what I have experienced with others in our TM3. When we (my wife and I) got it 5 years ago, neither of us had ever driven a TM3 before. We had a Ford C-max before. My wife got the honour of driving it home from the delivery center and I of course drove it a bit later. Quite a few friends and family tried it in the weeks after. I don’t recall anyone finding it cumbersome or hard to drive.
I do find it stupid that Tesla had removed the stalks on the refreshed TM3 and I welcome the Euro NCAP changes, that will likely have an effect.
