It is one thing to get absurd mileage with a specially prepared vehicle on a test track and quite another to get that kind of mileage in real-world driving.
For example, in these mileage competitions, it is common to accelerate the vehicle at full throttle to around 45 mph, then kill motor and coast. (Although this article says they ran at a constant 30 mph.) Obviously, you can't drive like that on the highway without inciting the rage of other drivers. The hybrids take advantage of the same principle, however: it is a well-known fact that that a gasoline engine runs most efficiently at full throttle. Hybrids use a small engine that operates constantly near wide-open throttle to get maximum efficiency.
Now, if all cars got 300 mpg, do you think gas would sell for two bucks a gallon? You'd have to buy it in fancy bottles, like Gray Goose Vodka, at 40 bucks a liter!
