Evidence: Under specific occasions google has had cars driving since 2009. Their cars have been driven more half a million miles without a crash. They arnt truely driverless yet they alert the driver when they need to take over the wheel when traffic is really badd or going through road work. Futurists believed the key to developing self-driving cars someday isnt just the smart cars its smarter roads. How much smarter did the cars ned to be? in the 1980s automakers used speed sensors at the wheels in the creation of antilock brakes. within a decade those sensors had become more advanced to detect and respond to the danger of out of control skids or rollovers. The information from the sensors could make the car apply brakes.
