Precisely.
I don't think many people have done the math on how cheap per-mile robotaxi services could be.
A $20,000 robotaxi amortized over 1,000,000 miles is 2 cents per mile.
The biggest savings is the driver. If you assume ~$30/hour labor cost at an average speed of ~30mph that's $1 per mile. Robotaxi will do it for a fraction of a penny worth of electricity.
Electricity is already cheaper than gas, and a fleet operator could purchase electricity at cheaper industrial rates (8c vs. 13c). 4mi per KWh at 8c per KWh is 2c per mile.
If you assume maintenance is the same as the capital cost (it's probably less) that's another 2 cents per mile.
Add these up, and you're at 6 cents per mile to build, pay off, maintain, and fuel up a car that can drive itself. 6 cents per mile is less than just the fuel cost of a car that gets 50 miles per gallon at $3 per gallon!
Let's triple that cost, to account for times when the AEV is carrying no passengers, and for a very healthy profit. 18c per mile retail cost. That's still less than the fuel cost of a 16.7 mpg car! It's probably less than the fuel+maintenance+taxes/etc of any fully paid off car.
With these economics, large portions of people in western countries will probably forego car ownership entirely. Two-car families will become one-car families. Poor countries, like we saw with cell phones where they skipped the landline phase entirely, will probably skip the car-ownership phase entirely as well.
