How Will Self-Driving Cars Change Cities?

In 1935, two years after his death, Fritz Malcher's 91-page manifesto was published by Harvard University Press. The Steadyflow Traffic System summed up the late engineer's ideas for resolving a dirty, dangerous problem: cars and humans trying to share space in the Depression-era American city. Malcher envisioned threading the city with wide boulevards, linked by U-turn ramps and roundabouts, on which a driver would never need to stop.
