WaPo reports on a rise in the inability of the police to adequately enforce so-called High Occupancy Vehicle lanes in the DC Metro area. This is an interesting phenomenon, and one I was not familiar with before moving to the area last August. Essentially, the leftmost lane on some of the roads are restricted to vehicles carrying two (and sometimes three) or more passengers. The idea is to give people an incentive to carpool but, since most people commute long distances to work and most offices don’t have enough people to make the odds of co-workers living in the same neighborhoods likely, it just rewards people who were going to have two people in their car, anyway. And annoys the people who are paying for that lane with their tax dollars but nonetheless have to now crowd into one fewer lane. That a lot of people get frustrated and circumvent the law is hardly surprising.
