Agreed 100%. Dollars are a greater concern than the environment. It's more about the money the the environment. The US gets nearly $50B a year in gas tax. The state (MA) gets about $750M/year on gas tax. As people move to electric and as efficiencies increase, governments will not tolerate a drop in revenue. They will raise the taxes to the point they can and will be adding a 'miles-driven' tax to everyone.
Similarly with cigarette taxes. Ostensibly those revenues (close to $1B per year) are intended to focus on targeted causes, e.g. anti-smoking efforts. In reality, the vast majority goes to the state's general fund and not any 'targeted cause'.
