Interesting Idea…from the Dutch

Certainly won’t happen in the current US political climate but its an interesting idea. Tax as miles driven in cars.
“Supporters of the meters contend that the charges are more equitable than current taxes like automobile purchase and registration fees, because they derive from actual use rather than mere ownership. If imposed, they could supplant gas and vehicle taxes as well as tolls. Governments could program computers to require consistent gas guzzlers to pay higher rates, for example.  “
