The slow but steady advance of driverless vehicles

Mike Johns didn't expect his return trip from Los Angeles to Scottsdale, Arizona in December to go viral.

To get to the airport he booked a driverless taxi and enjoyed a thrill when he jumped in with curious bystanders looking on.

But he got much more attention than he bargained for.

Mr Johns found himself being driven around and around a car park while those same bystanders looked on.

The Waymo ride was not doing what it should and there was no obvious way Mr Johns could fix it - and he had a flight to catch.

Mr Johns recorded the experience, a video that went viral almost immediately and was picked up on TV stations around the world, casting fresh public doubt about self-driving cars and how ready they are for real-world engers.
