The newest iDrive in the i4/iX really is pretty decent, particularly with the HUD, that Tesla still doesn't have.
I work in IT and I'm certainly not enamoured with the Tesla "techy" interface. While I find faults in all of them (Audi's MMI is very attractive, but the depth of the menus is nuts, for example), the interfaces on the e-tron, the Taycan, the i4/iX and the MB products do feel like an extension of the car; something that replaces conventional gauges, and they are all paired with a HUD. The big tablet in the centre just seems quite awkward in comparison, same with having to look away from the road to check your speed or see a map or any of the things you can see in the HUD on these other marques.
Tesla's lack of HUD and outside mirror BSM is a big ommission IMO. They are especially missed after driving our Lexi. The Tesla tablet is getting better in this regard, but again, IMO, falls far short.
My career was also in IT; initially I struggled with the Tesla interface as many do. Around here, in the early days you would see Model 3s at the side of the road with frustrated drivers struggling to perform tasks. These things are different, no doubt. Full disclosure, as a programmer I am a terrible computer user; I have never played a computer game besides Solitaire, and that was rare. I can barely operate Excel.
Today I use mostly voice commands while driving the Model 3. I rarely touch the screen. My point about the Tesla tech is, the future car customers take to the tablet interface naturally. I don't try to keep up with them.
While I have zero experience with the other modern interfaces that you mention, the Model 3's main driving parameters such as speed, speed limit, etc are right at top of the tablet, not much different than a traditional speedometer. And the amount of driving information such as number of lanes, surrounding vehicles, bike riders, and traffic objects such as cones is amazing. For the most part, after driving the Model 3 and then driving the Lexi, all those switches and buttons seem overly complicated. The Tesla interface is futuristic, far superior and highly updateable.
"Set the temperature to 70". "Turn the fan up." "My butt is cold." "Play Paul Butterfield." "Set volume to 10."
Perhaps try "Beam me up Scotty" or "Eject passender seat."
Having said all this, these cars are not for everyone. I tell people that all the time.
@OVERKILL , which way do you see cars going? IMO, Tesla is setting the stage for future cars. Software based design offers such promise, just as the Apple II and IBM PC did back in the 1980s.
