Express Lanes Have a Popularity Problem
Highway express lanes provide a faster trip for carpoolers, people who drive low-emission cars, and solo travelers who are willing to pay more. That’s the idea, anyway. But as Americans drive more miles than ever before, express lanes are facing a challenge: they are too popular. So many drivers of all kinds are using the lanes that it is increasingly difficult for transportation officials to keep them speedy.
