Electric cars seem like the perfect solution to reducing smog and our dependence on oil, except for one thing: Batteries just aren't all that great.<br /><br />While fast-charging systems like Tesla's Supercharger network can help, Daan Roosegaarde of Studio Roosegaarde in the Netherlands is looking at the problem from a different angle. Why are we focusing on the vehicles and not the roads themselves? After all, roadways are ubiquitous, and have the potential to be transformed into smarter, responsive interfaces.<br /><br />Enter the Smart Highway, a collaboration between Studio Roosegaarde and Dutch construction company Heijmans that introduces a prototype for what could eventually become the road of tomorrow.
