This would be true if fuel usage was linearly related to wear and tear on the roads, or road usage. Fuel taxes almost never tax heavy usage vehicles enough, compared to the amount of damage they do to the road. A fuel tax also doesn't solve the problem grandparent post is trying to solve, excess usage of 'high value' roads. If road usage, and road wear and tear, was evenly distributed then a fuel tax would work, but the reality is that is simply a convenient and fairly effective proxy solution. As technology improves a solution similar to grandparent, some form of usage tolling, will become feasible and provide a more effective outcome.
