What a bizarre rebuttal to see on HN. But I’ll respond despite the poor tone.

I took a guess of $2.50 per gallon in total net externality. Turns out after a bit of Googling a study out of Harvard University [1] put the number at $2.10. So, yeah I do believe it, seriously!

By the way, those $2.50 peanuts would add up to $360 billion per year in the US.

I don’t have a problem with a gas tax that tries to fully cover the externalities of driving, as long as the money is earmarked to actually try to offset the cost.
