The actual savings are minimal at best, as demand for cars is all about peak, and how the peak travels typically in similar directions. You see this in trains.

The actual savings are minimal at best, as demand for cars is all about peak, and how the peak travels typically in similar directions. You see this in trains. In downtown SF, you will find trains parked near the stadium all day, because there is no,practical use for them 9p% of the day. Most of the fleet is idle most of the day, and it would not be any better if it's a self driving car. You'd have a much better chance if trips were random, but they absolutely aren't. The nodes have been calculated and modeled, the gains round to zero. What you get instead is higher demand for moving around in cars, because it's now cheaper and less annoying. Lower prices increase demand, therefore more congestion, not less. This component obliterates said minor savings from earlier in any reasonable model.
