but they just pay it anyways since it's the cost of buying a "premium" vehicle. Or they use regular instead on a premium recommended/required vehicle.
Here's what might help along with that 14 cent premium gas increase.
Gas Taxes Rise in a Dozen States, Including an Historic Increase in Illinois
I don't know the quality of the information in that article, but it claims that 12 states just recently raised taxes. Some at minor rates, but states like Illinois rose by 19 cents.
so in illinois premium owners might notice as it's adding up. Maybe fuel taxes and some of these other things could help Tesla as they start to add up. Plus, i've seen other states talking about raising fuel taxes as well.
Edit: On the flip side, some state governments are greedy and charging more for EV registrations than gas vehicles. See Illinois as a new example. Not sure how all this will shake out and benefit Tesla if that's a new trend and they scheme to tax EVs at higher and higher rates.
