“No they’re not. They’re paid for with taxes on drivers who buy gas for their cars and pay registration fees. that’s not a subsidy.”
You are living in a dream world.
when my tax money is taken as a direct consequence of using a tax-funded service or infrastructure and goes to pay directly for that very same thing i use, it’s not a subsidy ... it’s a usage fee.
a subsidy is when the government takes my tax money and then gives it someone else, like when i as a very poor taxpayer have my taxes taken and given to very rich people to buy expensive Tesla EV toys ... THAT’S a subsidy.
