HAH!
that's hillarious,
I would love to see those cars holding up and slowing down traffic while "appearing" to look fast because they dont want to ruin their mileage

I would Love to cut them off ... err no that's not very nice...
I guess the whole era of people cutting off those Huge Ford Excursions who block your whole frontal view and hog up parking spaces are over, now it's time for the Prius Road rage: I just read this in the news; "Prius Road rage" is in now in LA's HOV lanes because they hold up everyone because they are trying to keep their mileage up.

One problem after another!
People created a car to save them gas, people buy them, people arent satisfied with it's exeptional mileage, so they drive them in a way where they can squeeze even more mileage out of it and in the process affecting other drivers.

Isnt that something else

regards,
