The drag force is roughly proportional to the resistance) will be important. The drag force is roughly proportional to the - velocity squared times the surface area of the moving object. So we should move + velocity squared, the surface area of the moving object and the air density. 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: - slowly, with a small surface area. + * Reduce the maximum speed of cars to say 60 km/h * Reduce the maximum speed of cars to say 60 km/h
