Honda's "eco assist challenge" is part driving game, part tutorial for Honda’s eco assist system that helps you drive in an eco-friendly fashion. A pop-up display warns you when you’re driving like a gas hog. The graphics are fantastic and the simulator takes you through three drives: city, freeway and country. Warning: If you blow through a stop sign, the game stops, which is unusual for a driving simulator, but not for a simulator designed to teach smart driving.
