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 have seen mobile speed cameras and cops with radar guns in school zones in wealthier parts of my town, and they pull over anyone more than 2kph over the limit
Wish I could say I’ve seen the same. I find it rare for people to do any less than 5 over in a school zone. The particular instance above was also influenced by the fact there is a highway entrance/exit about 1 km up the road from the school zone.
