More the fact that many states fund road work with a gasoline tax, this makes sense since it's got a decent correlation on how much use somebody gets from the roads. Electrics don't do this so states will come up short as more electrics get adopted otherwise.
My understanding is that road damage scales with the fourth power of the weight over the axle but fuel usage does not scale in the same way. In particular, heavy trucks do the most damage and of consumer cars, electric cars do more damage as they are heavier. Of course the people who most require roads to be constructed tend to be people trying to drive to or from their homes rather than large freight carriers who mostly require maintenance of highways.
