The recent tests of Google's self-driving car proved so successful that within days experts were speculating about the utopian world of travel that would be created were all cars autonomous.
However, a poll has revealed that some 58% of UK motorists would not be comfortable with surrendering all control to a computer.
The US state of Nevada recently granted the Google self-driving car its first permit. California is expected to follow in its wake, so it might well be the case that we soon see such technology on UK roads.
This is, of course, to be expected. People seem to be naturally suspicious of any new technology, and I can imagine myself being terrified were I to journey in an automatic car.
The sharp intake of breath and cold shivers that would accompany the first pull into traffic would probably persist for decades.
Indeed, the wonders predicted by the experts seem to be based on the assumption that every single car on the road will be autonomous.
Self-driving cars can relate to one another with breathtakingly beautiful synchronisation. But how would they fare were they sharing the roads with human motorists?
Should driverless cars ever become a widespread and accepted reality, they'll most definitely face the same teething troubles as are currently electric cars: The technology's there, but the world's just not ready yet.
Shame. Because just like electric cars, self-driving cars really do seem to have the potential to make the world a better place.
