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. my speed, acceleration, rate and harshness of braking, steering — all of these are being measured to see how i react along a route and predict any near misses that i have with other vehicles or people. and when enough cars behave erratically in an area, sensors are placed on lampposts to gather more data — which we will see later. but as a driver right now, i have a bit of a problem with the black box existing. if i want to misbehave slightly or go a little bit faster, i am just going to be constantly wondering, what is it picking up? is this going to bite
