It's not about maps, it's about operational design domain. The requirements for a self-driving vehicle on highways is very different from urban and and very different from sub-urban. Multiply that with how different countries and cities have very different looking roads, e.g. narrow windy roads in London vs wide straight roads in Phoenix. I agree it's not going to be an location-by-location rollout (other than for regulatory reasons). But I do think Tesla will find that their product "just works" in some places, and doesn't work at all in others - at least for a time. I don't think Tesla would sit on their hands and say "it's not ready yet" until they'd cracked everything. If it's safe to take a nap on Highways and not safe in an urban area then I think they'll just start selling that.
