For a fair comparison, hybrid cars can easily do 50+ MPG. For instance the "toyota yaris hybrid" is supposed to run 62MPG (3.8L/100km).

At recent US gas prices, 10,000 miles at 25 mpg costs less than $1600 in gas. At 50 mpg it's gonna be less than $800.

Most of the people spending $30,000+ on a new vehicle aren't going to be concerned about that difference, they are going to buy what they want based on other factors.
