Everyone who buys gasoline has the priced subsidized by at least $0.50/gal based on military expenditures used to secure that oil resource. That doesn't include various tax breaks the oil production companies use.
While I don't agree with CTLSi, that's a bit of a stretch.
Even if you don't drive, you benefit from gas. Some public transportation runs on it, or trucks.
And even if you don't benefit AT ALL, if we start tracing how taxes get spent and have to subsidize (reimburse) people that don't benefit from certain sectors, well, we can point fingers in every direction.
I don't think the reason it's subsidized is because they need to return the taxes you paid and got used for military to protect oil interests.
You could also go the other way and say that since electric car owners don't buy gas, they are not paying the gas tax but are using the roads supposedly (at least partially) funded by that tax.
I would love to own a Tesla though, don't get me wrong, they are really nice cars.
