Just to refresh:
Suppose that the price of gas is a function of supply and demand ... a
dubious proposition, but let's go with it.
Suppose that driver A and driver B have similar needs for "personal"
transportation: similar commutes, similar daily and weekly routines,
similar number of passengers per trip.
Finally suppose that driver A has a small car that gets 35mph/25mph,
while driver B has an SUV that gets 19mph/15mph.
Driver A is subsidizing driver B. It is driver B who contributes more,
proportionately, to demand, but yet pays no more per gallon that driver
A.
That's what I meant when I said in reply to Rick that his choice his
coming out of my pocket.
