Audi has become the latest brand to raise its game in the world of autonomy by today launching its new A8, which offers Level 3 technology - meaning it's possible to take your hands off the wheel.

That is, if it is legal in your respective country to do so, which is highly unlikely.

Imagining a future of self-driving where these obstacles no longer apply, Audi has adopted the phrase 'the 25th hour'.

This stems from its research showing that people worldwide spend an average of 50 minutes a day in traffic. So the 25th hour, according to Audi, is the extra hour you can get back if your car is self-driving. 

The car maker has carried out research to discover the perfect setting for passengers to get on with their daily lives while the car drives itself.
