So in 1885, Karl Benz invented the automobile. Later that year, he took it out for the first public test drive, and -- true story -- crashed into a wall. For the last 130 years, we've been working around that least reliable part of the car, the driver. We've made the car stronger. We've added seat belts, we've added air bags, and in the last decade, we've actually started trying to make the car smarter to fix that bug, the driver.
