So assuming we won't have [[https://en.wikipedia.org/wiki/Hyperloop|Hyperloops]] any time soon, we should move slowly, with a small surface area, ideally in a vehicle with a small drag coefficient. Some simple ways to make travel more energy efficient are:
  
   * Reduce the maximum speed of cars to say 60 km/h   * Reduce the maximum speed of cars to say 60 km/h
