I'll put money on a truly driverless taxi service being available in at least two US cities in under 5 years. The key with driverless is to stop assuming that it has to work everywhere in all conditions or else it's useless. What's actually happening is that the cars are being trained for and tested in specific conditions and locations where they will roll out first (dry, sunny, well-maintained modern roads, etc.), then as the technology improves, the envelope will expand until at some point in the future they do actually work everywhere all the time.
