Because most of us are taught (indoctrinated, really, but that's a rant for another time and place) to see digits further left as being significantly more important than digits further right. The style of pricing exploits this perception bias. And in the specific case of gasoline prices, since common US currency only goes to hundredths of a dollar, the thousandths digit doesn't seem relevant at all and rounding up takes more effort than most people are willing to put into it.
