Large margins and small supply are a lot easier to deal with though, and mass production is very expensive to set up.

Honestly we need regulation in this space. Incentivize building a cheap car so the manufacturers will do it.

Honestly the gov is in a good place to do this. Spec out a vehicle and place an order for a could hundred thousand of the them for general purpose government worker transportation needs. Set a low cost target. Let them build it for normal people too.
