GAO believes road surface maintenance should be paid relative to damage inflicted by travelling on it. Currently revenue for resurfacing is raised mostly by fuel taxes. Heavy commerical trucks are not found to be paying their fair share for the damage they inflict and high efficiency hybrids and electric vehicles pay much less and nothing respectively. GAO suggests a pilot study of gathering revenue per mile travelled using mandatory GPS tracking. One interesting consequence I found would be "metering" use of roadways by time of day to minimze congestion.
