Giving everybody a self-driving car completely defeats the purpose. Human-driven cars spend about 23 hours of each day just sitting around. A car that can drive itself doesn’t need to spend any time being parked - it can provide another ride! Liberally assuming a self-driving car would need to spend a full half of its time (12 hours/day) charging or being serviced, that would still mean that replacing all cars with autonomous vehicles could reduce traffic volume by a theoretical limit of 12× (12 hours/day/vehicle vs. 1 hour/day/vehicle).
you’re forgetting here that all people want to commute at the same time between 7am and 9am in the morning. so you can’t just operate 1 vehicle 24 hours around, you need the vehicles for these two hours especially and then some in the afternoon.
