We already know that Google has tested autonomous vehicles in northern California. In a widely reported incident, one of the Toyota Priuses was actually in a fender bender, although Google claims the car was being driven by a human at the time. The idea makes perfect sense, though: The computer in a car can react faster and use more diagnostic data than a human ever could. When a deer jumps out on the road, a Lexus GX 460 can use powerful forward-facing sensors to track the object, scan to see if you are paying attention (based on the angle of your face and by tracking your eyes and mouth), alert you with a chime, and even brake automatically in a split second – much faster than a human could.
