Electric-car drivers are saving the planet, right? Their vehicles produce none of the pollutants that dinosaur-burning, fossil-fuel-powered machines do. That is the standard view, and governments around the world provide incentives to encourage the uptake of this new technology.
 That is why a Tesla owner got a rude shock when he went to import his vehicle into Singapore — the first person to do so. Instead of an expected rebate of around S$15,000 (US$10,800) he received a fine of the same amount for being a gross polluter. The Tesla Model S is a 100% electric vehicle. It does not have an exhaust to emit from. So what happened?
