That is an interesting case that EV/HEV/PHEV do not contribute through fuel taxes, lower or none, while still using (aka damaging) the highway system.
The version I just looked at gives the costs as being $75 for any hybrid (HEV) and $175 for any plug-in (BEV/PHEV).
The question for BEV is 'how many miles does a normal ICE need to cover to generate that amount of tax'. For HEV/PHEV it is a question of the much better MPG we get from the ability to run on EV and the reduced fuel we pay. On an average owner, would those be a sensible number. The only other way to do it would be to base it on the number of miles made in a year - sum that for ALL vehicles (more for trucks etc) and then use that generate a cost per mile against the budget, and finally impose a tax based on that on the users. Somehow, I doubt that anyone would actually try to do that; at least not until we have all vehicles in the system with mandatory recording and reporting systems, and then it becomes easy.
Usual argument here is that fuel taxes are better because they relate to the amount to time actually using the highway systems, rather than an annual fixed cost. Certainly, we have restructured our system to make the major fuel using vehicles -SUVs etc - pay a much higher annual cost, as well more fuel tax because they are not so efficient vehicles. For a few years, we had a case that diesel had a lower annual cost and lower fuel, though that has now gone away. Of course with more EVs using lower or no fuel we are losing out on the income that they would have paid if using an ICE.
