The motivation, according to the bill’s preamble, is that the oil and gas industry is important to the state, a state with fewer than 600,000 residents. Wyoming is proud of its oil and gas industry, and that gas—here presumably meaning “gasoline” and not the natural gas referred to in the bill’s early sentences—powers vehicles that drive on the state’s vast stretches of highway.
Lol. Good luck with that.
