I assume one interpretation of 'ride sharing' is sharing the same pool of cars, but not the same car at the same time.

Sure, but then you'd still need a large number of cars to handle peak hours, like 7 - 9 in the morning and 15 - 18 in the evening. You're not really freeing up the road if you're not reducing the number of cars.

May be. But it may be that we share the same car/minivan.
