I've always found it odd that people would prefer an all-touch panel in a car. I find the knobs and buttons to be useful because they offer tactile feedback. I don't have to look away from the road to turn my volume up or to switch a track. The car is one of the few places where knobs/buttons make sense to me. Maybe I'll be eating my words in a few years.
Odd, I've had the exact opposite reaction. I will say from a functional point of view, it's excellent and feature packed. But from an aesthetic and consistency point of view, it still has a long way to go.
For example, it's as if there are actually 4 different UI's that share almost nothing [instrument cluster ui, center console ui, google maps ui, garmin ui (yes, there are two different navs)], each of which has it's own set of controls with a unique style.
That said, it's a great start (given they're such a new company and the ui is designed from scratch), and I'm excited to see what they'll have in store in the future.
Four suggestions: 1. Lenticular screen for a passenger's detailed view. 2. ?Infrared? sensor detecting which side is using it. 3. Anchor/dedicate screen space to controls. 4. Haptics with physical reference points. All should be relatively cheap to implement.
