Economist Mark Jacobson has estimated that for every mile-per-gallon we raise the standards, 149 traffic fatalities occur per year. That would mean 1,490 deaths if the standards were raised from, say, 30 miles-per-gallon to 40. But this doesn’t have to be the case. It’s possible, Jacobson has concluded, to increase fuel efficiency without also decreasing safety. And if government officials are smart, they’ll tailor the regulations behind the new standards to do this.
