The problem with these solutions is that the state where the miles are driven should receive the revenue. Soom road tractors will be EV and those states that would have normally collected fuel tax from diesel trucks will have a loss of revenue. Some states have proposed some sort of GIS tracking for proper distribution of collected EV taxes that would replace fuel tax.
Many states depend heavily on these fuel taxes to maintain their roadways. Tourist states like Florida use fuel tax as a partial substitute for income tax.
