text: Driverless cars are equipt with the latest in sensor technologies. Used collectivley, the sensors provide a model of the world around the car and not only enable it to mimic the driving of a human, but more effectivley and precisely navigate roads. This makes the car safer than if it were operated by a human driver. Current driverless cars aren't even properley driverless. BMW developed a car that can handle basic driving functions at slow speeds, but sensors in the car's driving wheel make sure that an alert human is able to operate the car in dangerous situations (i. e. car accidents or work zones). Even if cars are not fully autonomous, the technology being developed for driverless cars can assist a driver and help to avoid crashes. Google's test cars alone have independently driven over a half a million miles without any crashes.
