Audi Technical Development director Prof. Dr. Ulrich Hackenberg has revealed the controversial interior of the Prologue concept could be the shape of things to come.

Speaking with Automobile Magazine, Hackenberg said future models will have less physical controls such as buttons and switches. While this trend has been going on for several years, Hackenberg sees a day when everything will be controlled by touchscreens and cars won't have any buttons.

While the 2015 TT uses a digital instrument cluster with integrated MMI functions, Hackenberg said it won't carryover to all models. He declined to go into specifics but suggested sedans and crossovers will continue to have a separate instrument cluster and infotainment system.

Hackenberg also revealed their autonomous driving technology is progressing but they've discovered that drivers need up to ten seconds to take control of the car if there's a problem with the autonomous driving system. This is a potential safety issue as a lot can happen in ten seconds especially at higher speeds.

Audi is currently looking for solutions and one of them would reportedly involve using two computers to monitor the car's sensors and predict what will have next. If the two systems don't agree, they would ask the driver to take control. This sounds a little complicated but hopefully the additional lead time would allow the driver to take control before an issue occurs.
