Maintain Parity!

EV and Gas Vehicle USAGE TAXES: Vehicles have two impacts on the state. They use both the roads and the environment in their daily operation. Currently, Gas cars pay a road-usage fee via the Gas tax, but they do not pay for the environment they are using up. Similiarly, EV's pay a huge environmental benefit, but are not paying the road tax as shown in the graphic above right. Any consideration of adding a road-use fee to EV's should also end the Free-Ride that Gas cars get with resepect to their usage of the environment.

. Parity Today: For visualization, these charts to the right shows usage/consumption above the line and benefits below. Current impacts are shown solid, and future fees are shown hashed. As shown, both fossil fuel vehicles and EVs have a usage impact on the roads. Gas cars pay a gas tax for the roads but their huge cost in environmental damage is not being collected. Conversely, EV road fees are not currently being collected but EV environmental benefits are real. The pollution cost of the fossil fuel vehicles adds to their usage impact, whereas, the environmental benefits of the EVs shown in green tend to balance out their road load for a net-0 overall cost now. This apparent free ride for a few EVs is accepted now because of their significant benefit in reducing pollution. Considering environmental impacts and road usage costs, then, we can consider a degree of parity between gas and EVs today

Parity Tomorrow: But, as we consider possibly raising usage fees on EVs, to be fair, we need to also raise the pollution fee on fossil fueled vehicles as shown above (right). The solid colors in the figures are currently paid. To maintain parity in the future, the hashed colors need to be paid by both vehicles. As we raise the road fee on the EVs, there must be a comparable and equal rise in the pollution fee on fossil fueled vehicles.

The mechanism for collecting these fees is probably at the MVA. This new usage fee is the same across all vehicles per mile. To maintain parity, those fees from EVs should go to roads and those fees from fossil fuel vehicles should go towards renewable energy and the environment. The gas tax would continue to go towards roads and transportation.
