Infiniti EX35

As cameras and sensors continue to establish themselves in household robots, they're also bringing robotic technology to someplace consumers wouldn't necessarily expect: their next car. Right now, that technology has appeared in just a handful of higher-end models, but there's no reason to think that it won't soon be as commonplace as cruise control, power steering, and multi-CD changers.

For the 2008 model year, the Infiniti EX35, with a starting price of $34,850, showed up on the scene with a "lane departure prevention system" featuring cameras that keep an eye on roadway markings; if the cameras detect a drift, the system activates the antilock braking system on the opposite side to bring the car back on track.
