While we're still a long way from living the fully autonomous car dream, baby steps are being taken. The EU evidently shares this dream, and has passed regulations that will require new cars to have emergency self-braking systems (known as autonomous emergency braking, or AEB) if they want to achieve a five-star safety rating. The systems can use radar, laser or video to detect when obstructions or pedestrians are present, and a recent study suggests that the technology reduces accidents by up to 27 percent. Commercial vehicles will have to sport the systems from November next year, and everything else from 2014. Safety aside, we're thinking that anything that can help prevent rear-ending our new ride, is definitely a welcome addition.
