It's all good, indeed.
I was thinking about this more today. "Back in the day", I drove at rates well above the speed limit. My college roommate and I used to 'road ralley' from my house in Belmar back to college (Montclair), usually early Sunday AM so there was little to no traffic. He in his 84 Z28, me in my 82 TA. We liked to pull the 66 mile trip (mostly GSP) in under 45 minutes.
Well, one Saturday, we had a freaky spring snow. Now, by Sunday the roads were dry & clear from my driveway on out. So we did our usual trip. Well, there is a gradual bend going north near the arts center. Well, for whatever reason, literally right before that bend, I slowed down a bit and shifted to the middle lane, maybe I was f-ing with the radio or something. Just as we passed that bend, the whole left lane was snow covered. We would have slid right off down into the express lanes. Jeff pulled up next to me with trhis WTF look. We slowed down the rest of that trip. I can still picture it like it happened yesterday.
It isn't the speed that kills, it's the unexpected things out of your control (left turns, snow, blow outs, potholes, squirrels, etc.) coupled with the speed that does (well, technically it's the sudden stop that kills).
