Google has been building self-driving cars for years, but what we've seen so far has always been retrofits of existing cars — until now.
The search giant unveiled on Tuesday a fully autonomous self-driving car, built from the ground up by Google and its partners.
Company co-founder Sergey Brin revealed his plans at Recode's Code Conference in southern California. He told Recode editors Walt Mossberg and Kara Swisher (who has ridden in the car), that there's a safety benefit in a custom-built self-driving car. Because the car doesn't have a steering wheel, accelerator or brakes, it has more sensors in strategic spots than is possible in a regular vehicle. It is also equipped with a big "stop" button. In addition to all this tech, Google's autonomous car includes internal power steering and power brakes.
