How does the Land Rover Defender's Terrain Response system work, and what different modes does it offer?

The Land Rover Defender's Terrain Response system is a highly advanced feature that allows the driver to select different modes for different driving conditions. The modes include General Driving, Grass/Gravel/Snow, Mud and Ruts, Sand, and Rock Crawl. Each mode adjusts the vehicle's throttle response, transmission shift points, traction control, and other parameters to optimize performance in the given terrain.
