Many journeys, but few roads, are planned for leisure.
Functionalist doctrine has produced too many roads where the only pleasure is to reach one's destination in the shortest possible time. This runs against Robert Louis Stevenson's remark that "To travel hopefully is a better thing than to arrive, and the true success is to labour" (Stevenson 1881). A new road-type should be planned, like the original American parkways, primarily for the pleasure of bowling along at 50 km/hour looking at beautiful scenery and stopping for the occasional walk, swim or outdoor meal. The road surface should be porous, and quiet at speeds below 50 km/hour.
