The cause was easy enough to identify: Data parsed by Kuhls and her colleagues showed that drivers were speeding more, on highways and on surface streets, and plowing through intersections with an alarming frequency. Conversely, seatbelt use was down, resulting in thousands of injuries to unrestrained drivers and passengers. After a decade of steady decline, intoxicated-driving arrests had rebounded to near historic highs.

… The relationship between car size and injury rates is still being studied, but early research on the American appetite for horizon-blotting machinery points in precisely the direction you’d expect: The bigger the vehicle, the less visibility it affords, and the more destruction it can wreak.

    I’ve also heard of arrays of cameras being used along an entire street. So even if you aren’t speeding at one camera, it will know your average speed across the whole street and if you were speeding between cameras.

      Yep. Average speed cameras. They work great on roads with no exits or turns for a while. They detect your time entering the zone, and the time exiting and work out your average speed

      They don’t work on city streets as 1 minute at a red light, or even 15 seconds traversing a roundabout, messes up the average

      We also have aerial speed checks - a plane circling above a highway identifies speeding cars and radios to police ahead.
