Google Cars Drive Themselves, in Traffic

Im reading the article abt Google Cars Drive Themselves, in Traffic.. i pick this article because it looks intresting of how the google car drive them self on the street to go throw each street in each state. the quote that was intresting is "Robot drivers react faster than humans, have 360-degree perception and do not get distracted, sleepy or intoxicated, the engineers argue". i pick this qoute because it is true that us in person we do get sleepy in distracted... but they hav put robot people to drive this carr n so they dont get distracted. this article is cool because this cars have alot of cammras so it can get all the streets n house so they could put it on google earth/map. this whole article is abt technology of how we use it when we need it n where yhu could fine new places that yhu havent dicover.
