Some enemies will run away at the sight of the vehicle, eliminating the need for Batman to fight them, and enemies attacking the car can be subdued by its automated taser defenses. Like Batman, the Batmobile can be upgraded with new abilities. The Batwing is used in conjunction with the Batmobile to deliver upgrades, while providing real-time surveillance and close air support. Riddler challenges also feature objectives requiring the Batmobile, such as timed races in tunnels beneath Gotham City, where the environmental obstacles change during each lap, and invisible question marks that must be revealed using the Batmobile's scanner.
