I generally agree with your overall argument; my own wording was a kneejerk. I was trying (probably too cleverly) to differentiate speed from speeding. For me 'speed' is quickness, as opposed to 'speeding' which I regard as driving too quickly for the road/weather conditions/driver ability - regardless of the speed limit. 'Tis in that context that I still maintain that speeding kills.
