Biden discarded all of Trump's Executive Orders regarding energy production and restored Obama's failed energy policies with the stroke of a pen his first day in office, when he signed Executive Order 13990.

You're right that gas prices were even higher under Obama, when adjusted for inflation.

However, the discrepancy is much more apparent between Biden and Trump policies than it was between Obama and Bush, mostly due to the Iraq War and Hurricane Katrina and the 2008 economic collapse all boosting the price of gas before Obama took office. And Obama had the BP oil spill he could blame as well, and more people bought that excuse because there was at least some basis in reality for it.
