Yes. Roads are subsidized; the true cost of building and maintaining roads comes from general funds, not just from vehicle registrations and gas taxes (which of course Waymo doesn’t pay, being righteously electric).
So you pay Waymo, they pay a few hundred dollars a year per car in registration, and you benefit from billions of dollars a year in highway funds from both state and federal sources.
Good point about electric. Maybe a tax on tires would be more fair, but that would lead to some dangerous behavior.
Waymo and I pay a lot in state and federal taxes. Shouldn't that work out that we're paying for a shared resource we use even if the proportional accounting is not exact?
