Two problems with your suggestion: 1)not enough truck drivers, nor trucks to move that kind of volume (this has existed for nearly 2 decades and getting worse - google it). 2) refining CAPACITY isn’t sufficient or they would already be doing what you’re suggesting. Upgraders, refiners are UBER EXPENSIVE to build, and NO CAPITALIST is investing in new refining capacity for the last 10 years. This is why most of the refining is done where it’s already built.
