Indeed although many have much more inclement weather than Phoenix. To be clear, this is good progress. But expansion may be slower than many think.
And also lots that are an incremental step away. Gotta start somewhere.
A non significant chunk of trips are in places that don't look like them. If I still need a driven car for 10 or 20 percent of trips, I'm not going to ditch in favor of driverless cars.
It's a service, like Uber, you're not expected to ditch the car at this stage
If it gets cheap enough I at least could take the self driving car to the nearest train stop and go downtown via train. She got grocery shopping in the suburbs. However, shopping be better only a single stop. Maybe we could solve that problem though by having some kind of bin that gets automatically stored at a grocery store while I'm shopping, loaded with my groceries and then put into the next self driving car...?
