With buses you would still have traffic problems even if in theory it would help reduce traffic. As long as we have humans driving vehicles, there will traffic.

With buses you would still have traffic problems even if in theory it would help reduce traffic. As long as we have humans driving vehicles, there will traffic. Realistically, this won't change any time soon (probably never). It is much faster to get from point A to point B with rail (metro, for example) than a bus.
