Not that long ago, collision avoidance systems were available exclusively on German luxury sedans like the Mercedes S-Class. Fast forward a few years and suddenly the technology is a $295 option on the 2012 GMC Terrain.

Not that long ago, collision avoidance systems were available exclusively on German luxury sedans like the Mercedes S-Class. Fast forward a few years and suddenly the technology is a $295 option on the 2012 GMC Terrain.

Recently unveiled, the system uses a high-resolution camera to scan the road for vehicles and lane markings. By comparing photos, the system can determine if the driver changes lanes without signaling or is going to rear-end the car in front of them. When this occurs, an audible warning and a visual display is activated to alert the driver. Furthermore, if a collision is imminent, the system primes the brakes for maximum boost to prevent or reduce the severity of a crash.
