The saving money comes from saving lives, not the other way around.

Public transport and car sharing are two sides of the same coin. They approach the same solution from two different avenues. Public transport does not address the "last mile" problem of getting to the bus stop. Solving this issue would require more stops and smaller busses with complex adaptable routes. This is cost prohibitive if you have to have drivers. Car sharing is expensive and inconvenient because cars often end up parked in places were they are not needed and parking itself is expensive. Self driving cars (which will naturally evolve to mini busses) solve all these problems. No parking, no making grandma, and expectant mothers walk a mile to the bus stop. Everyone gets a cheap chauffeur service. And massively reduced road fatalities.
