Even if the price of gas were much lower, you would still see a reduction in miles driven simply because 23 million unemployed or underemployed people have no reason to drive as far as those who have to commute to a full-time job.
Does this mean that demand is determined by price, and the slope is negative? Others have tried to convince me otherwise. (Especially noting that mileage per gal has generally increased.)
No GPS tracker in my vehicle... or is there?
