The sketch you see above is one of a future Audi A3 Sedan. Ignore the funky steering wheel as it may be drawn that way to show the rest of the dashboard. And what do you actually see? A dashboard devoid of signal switches, wiper stalks and gear knobs. We already see a lack of gear knobs and shifters in the latest BMWs, Mercedes' and Jaguars. This has turned into a rotary selector on the transmission tunnel. And according to Audi the dashboard you see is how the envision their future interiors to be, slightly different from what we expect these days.
We will also see wiper stalks/controls going missing as when most cars adopt automatic rain sensing wipers and then light switches going missing too when all cars adopt light sensing automatic headlights and cars that will detect lane changes and auto signal (this may happen eventually).
And then you add the fact that you now have multi-media systems in the car telling you the temperature, location, air conditioning and entertainment in one screen (which will be touch sensitive and voice activated soon) and everything will be controlled through it soon. You can either scroll through a smartphone like interface to reach for the wipers if you want them on manually or you can do that Star Trek thingy and say 'Computer, wipers on to full. Rain factor heavy'. And so you do not need hand controls any more.
And before you know it, car manufacturers will get rid of the steering, brake pedal and throttle pedal too. Everything will be automated and hidden away. Remember the Audi R90 that was featured in I-Robot? That Will Smith movie with the futuristic Audi (pictured below)? He had the option to over-ride the computer to drive manually. This is the future and it isn't that far away actually. Whether we like it or not, as is usually the case. And since all of these changes omit lots of 'unimportant' stuff, can we expect larger and deeper cupholders for those extra large coffee cups?
