Over the next decade-plus, American motorists will find new fuel-efficient cars and trucks in showrooms that offer them the advantage of going twice as long between fill-ups.
The estimated $8,000 in fuel savings over the life of a vehicle from that technological gain alone makes the Obama administration's launch this week of new vehicle mileage standards a milestone event - the first such boost in more than 30 years.
But for an estimated 500,000 people, the mandate that automakers achieve an average fleet fuel economy of 54.5 miles per gallon by 2025 also means they'll be driving to new jobs.
