First, smart cars. Next, smart transport grids

Haunted by the nightmare of global traffic paralysis, Ford Motor executive chairman William Ford Jr. has a global dream.
Given current growth trends, the world’s population is expected to reach 9 billion people by midcentury. That also means a quadrupling in the number of cars to 4 billion by 2050 — and that, said Ford, is a recipe for global gridlock that he argues will become “a human rights issue, not just an inconvenience.”
