That's an issue of supply. Technically, the demand is high. I don't know a single person who has ever considered walking to the grocery store or bicycling to work or even, GASP!, jogging to the gym. Rather, they prefer to bitch about how much gas costs....as they trade in their Focus for an SUV.
So, technically, demand is high. It is obvious by the fact that people are paying 300% more than gas cost 4 years ago. It may be a falsely inflated price, but if they can get it, then more power to them, I guess.
