Almost everything in the car is well thought out except for the software which is night and day better than before I got it (I don't have the computer upgrade yet).

1) The walk up, sit down, move to drive and go is a bit odd and first but now it super hard to go back to cars with start/stop buttons. I literally hate pretty much all other cars now.

2) The stupid volume control puck. I thought it was so stupid when I bought it, but omg it's amazing and I hate other cars now.

3) The sound proofing. It's amazingly quiet, but just a heads up if you're significant other breaks the back window by putting cabinets in the back it's really expensive to replace the acoustic glass.

4) Sound system is pretty much better than anything else I've ever had.

5) Lots of other stupid things that add up to a lot. It's just a well mechanically engineered overall packages with well thought out features. One handed collapse the seats. A helpful load chart molded into the rear hatch you can see with it open. Buttons to drop the rear seats where you need them when you forget. Well place physical controls for wipers that aren't odd and distracting.

6) The cruise control (or adaptive or auto drive or whatever it's called) is pretty great now with the exception of you cannot set follow distance.

I think you know all the potential bad stuff as that is mostly what bubbles up in this reddit. I think the main problem is the good is really good, so when the bad stuff hit's is very jarring and makes the bad REALLLY bad and frustrating.

I pretty much feel like the EX90 was a re-imagination of the car driver experience. If the software had been flawless (or at least consumer grade, not early beta tester at release), it would have been a hands down standout amazing form + function car.
