Except that the congestion caused by individual drivers on roads (even with each car fully loaded) is far greater than that caused by mass transit vehicles such as buses, trams or trains. And as congestion increases, the cars spend a lot more time waiting in gridlock, and a lot more fuel is burnt than in the theoretical optimum.
Also, I doubt that the Cato Institute would be particularly impartial here.
