Hand gestures for common functions
The UX to find/manipulate settings while driving a model 3 is pretty painful, distracting, and borderline dangerous. If I want to turn the volume up, I have to carefully point my fat fingers to a 5mm x 5mm square on the tablet at the risk of driving off the lane. Sure I could use the toggle on the steering wheel. Sure I could be driving on autopilot so I don't get distracted. But hopefully you get the point? It's absolutely frustrating to click on menus and submenus to get to common settings.
I would love to see hand gesture controlling common functions such as turn on/off A/C, temperature up/down, volume up/down, song prev/next, like/dislike song, etc. My right hand on the arm rest is perfectly positioned to provide one-hand gestures that the cabin camera can convert to controls.
