I’d like to offer a possibly controversial alternative viewpoint on this. On a longer time horizon than just the past few years, we saw the introduction of touchscreens for drivers way back in the early 2000s. We just called them smartphones. Before that, rush hour commuters could be spotted reading newspapers, shaving, applying makeup, and eating breakfast while driving. All of those pose real dangers to themselves and others. My point is that the fundamental issue at hand is more significant than the UI / haptics of the car, but the attention paid by the driver. Humans have already cast their vote on this. As drivers, broadly speaking, we do not want to give the action of driving our full attention. There are simply too many other things vying for our focus. The solution, in my opinion, is not about the controls in the vehicle. Rather, it’s about removing the distracted driver from the equation altogether and finally mastering the immense challenge of truly autonomous vehicles. We are at a point in history where the UI/UX has advanced faster than true self-driving. If the latter can catch up, the UI will become a non-issue, the screens will continue to grow, and the driver will merely be an operator.
