So far, the cost of building/maintaining the traffic infrastructure (roads, bridges, etc), is largely met by the surcharges on the gasoline purchased by non-EV car owners. Those surcharges make up around 50% of the fuel cost. The electricity used in EVs would, eventually, if EV sales take over, have to be raised to cover the infrastructure construction/maintenance, thus eliminating their present cost advantage. Is this taken into account by the EV promoters?
