How to tell if a car is truly driverless: Has it got a steering wheel?


One of the biggest barriers to the successful introduction of driverless cars is confusion over what constitutes true self-driving.

In America, the controversial autonomous vehicle expert, Alex Roy, has suggested a self-driving litmus test called Roy’s Razor. “Can you get in, pick a destination and safely go to sleep?” he asks. “If yes, it’s self-driving. If no, it’s not.”

While this has some merit, the key word “safely” gets somewhat lost. The internet is awash with less than sensible people climbing out of the driver’s seat with their Tesla in Autopilot.

So, here’s an idea to head off such recklessness… the best way to tell if a car is truly self-driving is to ask this simple question: Has it got a steering wheel?

Audi has apparently been down this road in the thinking behind its new Grandsphere concept car. When in “hands-off” mode, the steering wheel folds neatly away.

That certainly removes any doubt as to whether the driver is responsible for driving or just a user in charge, to use The Law Commission of England and Wales’ new lingo.

“We will be ready for Level 4 driving in the second half of this decade,” said Josef Schloßmacher, Audi’s spokesperson for concept cars.

“That’s an important timeframe for us and we will interact with authorities in the different continents and countries in all important markets on the homologation of this new technology.”

While somewhat open to the accusation of a fudge – if it is truly self-driving, why do you need a steering wheel at all? – this looks like progress.
