gasoline down, diesel still sky high?

For discussion, notably we are seeing energy coming down, but products and food are still elevated, food especially in Canada continues to rise.

Interestingly, gasoline has dropped in price at the pump, helping consumers with inflation, yet diesel remains persistently high despite in some economies like North America it is a lesser used vehicle fuel other than for large vehicles such as trains and trucks.

Any thoughts or reasons why gasoline is dropping yet diesel remains high? The 2 normally track together as oil and fuel supply and demand are linked.
