I think there's a question of what bar you're trying to reach. The mid-teens driverless car hype seemed to promise ubiquitous driverless cabs everywhere. I think what people will expect is that you can call them and they'll come any time a human-driven Uber would come. By that I mean on a rainy night, or in the winter in a northern city. I really would like to see them operating year-round in someplace like Boston or, better, Pittsburgh (SF-like hills but with snow).
