This is some boomer nonsense. I can't find 2 sources that seem to agree on specific numbers, but several sources, and my personal experience, agree that gas prices peaked in 2008 after the one two punch of Katrina and the housing market collapse
I started driving in 2006 and bought my first car in 2008 and I can confidently say that I'm paying less for gas now than I was when I started driving and I'm not even talking about adjusting for inflation. Are prices too high? Yeah, probably. But this "then vs now" shit just ain't true
