Many thoughts here, I’ll try to address them in turn.
1–81% of americans live in urban environments, and that will only increase. That’s the logical first market. Rural areas will come later, but can be served by AEVs soon and will thus increase mobility due to low operating costs.

3-Buying cars already doesn’t make sense. If you can hail one and get to work for say $5 each way, then is $300 a month for that less or more than current car payment/gas purchase/insurance/registrations/repairs?
