moving other stuff out of the way to find it. i wonder if it tidies up afterwards. right, self—driving cars are not a common thing yet, and one of the main reasons is because of concerns about safety — although saying that, 90% of accidents today are due to human error. but today, one car manufacturer is using data to help make roads a little bit safer while humans are still behind the wheel, and they are doing that by using sensors to track dangerous hot spots. this is a proportional integral derivative controller — pid for short. they're more commonly known as black boxes and are being used today for something other than insurance purposes! yay! ford are working with vivacity labs, using these pids in their cars to monitor my driving in order to assess an area's road safety.
