That company isn’t an automaker, either. It’s Google.
Google’s autonomous car experiment uses video cameras, radar sensors and a laser range finder to navigate its cars driverlessly. Most of this technology is already used on some adaptive cruise control and emergency mitigation systems in luxury cars, but Google’s system goes a few expensive steps further. Google’s system uses detailed maps (which, from the way the company describes it, sounds like a high-def version of Google’s street view) to navigate the road ahead.
