I don't think it'll make much economic sense for consumers to actually buy them, but I do expect to see services accessible to the public that let you use an autonomous vehicle in places with effectively ideal conditions before 2030. I also don't regard that as a particularly significant advance in the broader sense of the objective because I think it's easier to get from zero to driving in Phoenix than it is to get from there to handling, say, traffic in Mumbai, both in technological and social terms.
