This sounds incredibly wasteful. I doubt car sharing (self driving Uber) will be workable if the fleet has to be sized to 2-3X number of households.

Instead, wouldn't it be more reasonable to assume a mix of real public transportation and increased amount of telecommuting?

Even though parent was referencing number of cars, having "enough" cars has never been the issue - the problem is traffic congestion and other externalized costs inherent to having a car per person.
