The fact is that you don't have to look at all, because the Tesla touchscreen does not have modalities. (There is a drill-down menu that you NEVER need to open during driving). Everything else is accessible in exactly the same spot at the bottom of the screen and no looking is required.
Additionally, as I said, the steering wheel buttons handle everything that matters, so there is no need to even interact with the touchscreen at all during driving.
Let's look at the interactions in detail:
- Most controls of the car are done using physical controls. This includes left and right blinking, reversing, steering, lights, wipers, honking, the acceleration and break pedals, windows, seats, doors, opening compartments, audio and media controls, autopilot and lane keeping, camera controls.
- The only things where interaction with the touchscreen is preferable are (a) setting a destination in the navigation system - for going home or to work this is literally a swipe gesture on the main screen, usually done before the car is started and (b) adjusting the heating or temperature. For this there are two buttons at the bottom of the screen, always in the same location. However I always have them on auto and there is simply no need to fiddle with this, ever. If it's important to you it can be configured to be on the steering wheel as well.
- I think people who think that constant adjustment of the temperature settings is necessary are used to driving cars where this is not sufficiently automated. I have seat and wheel heating set to auto and that works just fine. I have set my temperature to 20 °C and it feels comfortable in summer and winter. Why would I want to change this while driving?
- Setting a new destination in the navigation system can be done using voice. This is not great but will certainly be improved. A modern system like Whisper should handle this easily. In any case, why would anyone want to do this while driving? And in any case it will be the same issue in any other car, because this simply requires typing out letters which is difficult.
> I would argue worse than "text and drive" smartphones.
Obviously holding a phone and typing out text on a tiny keyboard that certainly has to be looked at takes far more focus than touching a pre-defined spot on a huge fixed screen. But as I said this is never needed.
