I interpret "car sharing" as more about keeping utilization up. When you're at work, the car you used to get to work will be off doing something else during the day. When you want to go back home, it could be a completely different car. You'd pay a subscription for a certain level of car service (time responsiveness, cargo capacity, comfort level). Maybe you'd get a discount for scheduling your commute a week in advance. The # of cars on the road might be the same, but the amount of resources we would consume as a society would be lower. Or maybe it would be the same, but the flexible model would allow scenarios that weren't previously possible (e.g., your child could "drive" to school without you).
