That's because you're restricting the ICE to gasoline. I believe you don't need a refinery to produce ethanol from sugarcane (ethanol-fueled ICE vehicles are common here in Brazil); I don't know much about diesel, but you might also not need a full refinery to produce biodiesel.

I'm going to say that a solar panels and some kind of battery are still sound easier than growing and refining/brewing sugar cane into ethanol. To me anyway.
