Thing is, the largest market segment in the U.S. are for family cars (cars that can seat at least 4 people). The Insight seats only 2. The average American household with Mom + Dad + 2.1 kids and limited disposable income are not going to consider the Insight when shopping for a new car.That's one of the chief reasons the Insight sold poorly, which is why Honda no longer makes it. In contrast, the 4-door Civic Hybrid sells quite well-- It's a more versatile vehicle.
