In practice, if you provide enough cars to meet the demand to travel from suburbs to city at 7am-9am and back again 8 hours later, I’d expect a large fraction of them to be idle outside of peak hours. And even at peak hours, to be spending half their time empty, as almost all the demand is in one direction.
And if you don’t provide enough capacity to meet rush hour demand? Good luck convincing people to give up their cars.
