"We are asking you, essentially, to become transportation hackers (and we're talking not simply cars but the whole of urban and interurban movement). We are looking for your best ideas. They may be your own wild brainstorms, or they may be examples, whether grand or mundane, of things you've experienced in your own city or while traveling. But we want your best proposals for solving an increasingly relevant problem: how to move the most people around and between cities in the most efficient, safe, and perhaps even pleasurable manner. And then we want you to vote on which of those submissions you think are best."
Ideas already submitted include making cars slimmer, making cars autonomous and making different road rules for cyclists.
