It's always interesting how these things are worded. Rather than say there's X amount of them now active and information about it, it's compared to a company that has little reason to invest in a market that most of the US doesn't care about.

The city I live in has 400,000 people, so not like a huge city but not BFE. We have zero taxis automated, and no "human" taxis driving around. We have Uber and such still. Point being, there's only like a dozen US cities that actually use taxis regularly and this might be realistically viable. Tesla just doesn't care in general, the hyper loop failed massively already for them.
