ANALYSIS AND OPINION: One of the fringe benefits of golden state citizenry is you get exemption from occupancy rules on California HOV lanes if you drive some kind of electric plug-in. But lately too many single occupant cars are clogging up the lane. They need to narrow the criteria. They started by asking WHO should be allowed access? Instead, maybe Californians need to start a national conversation with a reset to ask exactly: WHAT KIND OF ELECTRIC CAR should have access?
