Gasoline is about $3.50 per gallon today. In 54 years, if you experience the same inflation, it will be $28.34 per gallon. Of course, some of the powers that be want you to be in an electric car or have all cars banned by then. I saw a new Camaro advertised online for $41,370. Well, that will cost you $344,985.05 54 years hence.
