They should do that here, not with hills but with against-the-flow commuting. I don't mean riding against traffic. I mean we have a big problem with Citibike, NYC's bike share program, which happens to use the same bikes as Velib. The problem is that some stations don't have bikes because they are popular pick-up spots. Others are full, because they are popular drop-of spots. It's similar to the parking problem in cities and to crowded subways on popular routes. Someone just mentioned they should have incentive pricing. I don't know how we should implement it, but I like the idea. They started out balancing the bikes with trucks, and they still do that. But trucks can't slip through traffic, and traffic in NYC is insane. So now they also have bikes towing trailers, where the trailer can hold four bikes. Imagine having that job all day long, balancing the docking stations on a bike.
