"each one should be investigated as if an accident occurred and fixes proposed"

I feel the same way about close calls on the road, especially ones involving a vehicle and a vulnerable road user like a pedestrian or cyclist. Way too many lives being saved by a person jumping out of the way at the last minute who shouldn't have had to do so, and then cops and bureaucrats shrugging with "well what do you want us to do, the numbers don't show enough fatalities here for it to be worth fixing" and later when someone actually does die it becomes "this is a horrible tragedy that no one could have seen coming, let's focus on thoughts and prayers rather than accountability that could lead to structural change."
