New national standards only allow "hybrids that improve mileage by 50 percent in the city or 25 percent overall" into high-occupancy vehicle (HOV) lanes. For this reason, Ohio has excluded the Chevy Tahoe hybrid (which only improves mileage by 40% overall to a whopping 21 mpg) from its carpool lanes.

This raises the question - who should be able to use carpool lanes? Should all single-passenger hybrids be excluded, or should there be some sort of mileage cutoff (such as 40 mpg), or is the current standard (described above) the correct one?
Why should a 32 mpg Ford Escape hybrid be allowed to use the carpool lane while a 32 mpg Toyota Yaris is excluded?
