I'd feel far safer in a driverless taxi than I would in the cars of quite a few taxi drivers that I've travelled with!
For example, some years ago a local taxi firm around here had a driver who only knew two speeds: 'stop' and 'go'. He'd drive at about twice the speed limit and then charge his passengers about 50% more for the journey than any of his colleagues did.
In Lille I travelled in a cab, in busy city centre traffic, where the driver was not only speeding but watching a movie on the screen below his dashboard at the same time!
