What if you could outfit a fleet of taxis to be driven by remote over the internet? You could outsource your taxi driving workforce to India without importing any people. Or perhaps this would work better as a driver hire service for your own car, until someone takes it for a virtual joyride and the extradition rules aren't clear. And the network connection would have to be pretty reliable, too. But apart from those major deal-breaking issues, not a bad idea, eh?
