 Clearly, not all car trips can realistically be replaced by cycling.
 However, 5 km Euclidean distance (or around 6-8 km of route distance) can realistically be cycled by many people, especially if they are riding an electric bicycle ('ebike').
 We will therefore only route desire lines\index{desire lines} along which a high (300+) number of car trips take place that are up to 5 km in distance.
