They already have it. What they need is to take the hint and make the local bus system useful. It shouldn't be more than 10 minutes from when you get to the bus stop until a bus arrives. The bus should go a straight line. This can be either the downtown transfer point, or a grid - either with timed transfers so that when you arrive at a transfer you get on the other bus just before it leaves, or if you are continuing on you don't wait very long. Either way, a bus system can do much better than most do.
