So if egregious accidents will contribute to 'knee-jerk' changes regardless of traffic laws, it is indeed a non-argument and a strawman when considering the case of changing the way traffic laws are set. I poorly supported that with the traffic deaths dropping bit, quite true. Separately, it would be more apt to observe that traffic speed limits set not with respect to natural driving speeds are shown to increase traffic collisions, because speeds set too high will have some drivers naturally driving far too slow to be safe, and speeds too low will also have drivers driving too slow (the posted limit) versus the natural speed of the road which some will drive.
