Google has been working on its driverless cars for quite some time now and if you happen to have been on the right street in California at the right time then you might have even seen one of the prototypes doing the rounds. If you'd looked really closely you would have spotted a rather ashen-faced human babysitting it, too. But the worst kept secret of it all was that Google didn't have any fully automated cars to call its own. That's now changed, with Google producing a prototype that has all the usual functionality that you might expect from an automobile. That means it starts, stops and turns corners, then. It's the stopping part we're most interested in at this point though, if we're totally honest!
