Eventually, your savings on gas will be completely gone,
and that $100 penalty you're paying for using EVs, will become a lot larger.
What will happen is that, you are going to be charged by tha amount of driving you do, in order to extract an equitable amount of money from you for the amount of driving you do. Call it the "road usage" tax. In the end, you'll end up paying approximately the same in "driving taxes" as someone who is paying those taxes via gas taxes. Eventually, the taxes will be shifted from gas taxes altogether, to "road usage taxes", which will bring in more revenue to the government coffers.
