Paying for the road-time you use, like any shared resource, seems fair to me. It would be nice to see decreases in earned income taxes though.
If the retort to this is it impacts poorer people more, then that is a separate problem fixed by redistributing more cash, so that the wealth gap is smaller.
Edit: to respond to reply about trucks causing more damage to road:
Construction costs are one cost of roads, but another cost is time cost due to congestion (and resulting effects of delays due to congestion). A variable rate toll that also incorporates congestion is the ideal way to manage road use, much like paying more for electricity or other resources at peak demand to modulate demand.
