Just think, UK could have been king of the drone market, but instead they made a bunch of micro regulations to limit any freedom in that. And the police screamed drones = thieves.
Autonomous cars will be next, a bunch of hysterical people will scream murder at the first minor accident and a lot of regulation will follow that kills all the potential in that market (for the UK at least).
Or perhaps the spooks and police will demand mass surveillance be attached to cars so they can monitor them... for our safety so nobody wants them.
Welcome to UK, Cameron has failed, he's made the state more Nanny than ever before.
