Fuel tax revenue and other direct user fees like annual registration in California amount to less than 25% of what the state and its cities pay to maintain the roads and streets. Roads are massively subsidized from general revenues. If you are proposing a $5/gallon fuel tax then I completely agree. That would be about equivalent to what other rich countries tax motor fuel and consistent with the state's greenhouse ga…
That's misleading -- yes, in the aggregate, gas taxes cover only part of the expenses, but that's not because of personal cars . Damage on the roads -- and thus maintenance costs -- scales with the 4th power of weight per axle. So the damage is virtually all from large trucks, with sedans and SUVs as a rounding error. If you were to apportion out the maintenance cost due to personal cars, they are overpaying.
The state effectively charges for the use of roads both to pay for maintenance and to make sure that the road remain usable to a reasonable cross-section of people. This is just as landlords charge for the use of land even when that land isn't consumed.
