There are two technologies, and both are options. We get them as part of a package but in other markets you can opt for Lange Change Warning, Lane Departure Warning, or both. However both rely on KAFAS. In both KAFAS monitors lane markings to determine if you're drifting or changing lanes, and then in the case of LCW, uses the rear sensors to determine if there's another vehicle next to you.
In earlier generation cars, you could actually have BOTH cameras (KAFAS and AHB) depending on your packages, but KAFAS has improved now to where only a single camera is required if you have the options.
Unfortunately with just AHB, the KAFAS module is too expensive so they still use the standalone camera.
