This bill matters to voters because it directly addresses a potential new type of tax that could change how everyone pays to use roads. Currently, road maintenance is largely funded by gas taxes. However, as cars become more fuel-efficient or switch to electric power, gas tax revenues are expected to drop, leading some to consider mileage-based taxes as an alternative.

If this bill becomes law, it would ensure that the federal government plays no part in developing, promoting, or enforcing any system that taxes drivers based on miles traveled. This would likely slow down or prevent the widespread adoption of mileage taxes across the country and keep the focus on current funding methods. If it doesn't pass, the federal government could still use its resources to research, develop, or even help implement mileage taxes, which could lead to new fees for drivers and new ways their driving habits might be monitored.
