While you're underway there aren't many other things you should be keeping an eye on, but that was an absolutist stance to make a point. I know people are going to be glancing at fuel or temperature or whatever. > I would've said that the speedometer really isn't needed - if you go with traffic and don't hang out in the passing lane, you're never going to get in trouble That's really location specific, and situation specific. We can't go over ~5kmph faster than the limit here without getting fined by speed cameras. Also 10kmph faster on a highway versus 10kmph faster in town are very different. 10kmph faster in town could be the difference between killing someone or not hitting them at all. I do somewhat agree though, I think "driving to the conditions" for me personally would be totally fine, I'd probably trend to driving slower than the speed limit. But if you had no limit and no enforcement, people would be abusing it all the time. Someone in a hurry in town would easily cause trouble. The tradeoff for limiting that is having to check your speedometer. 10kmph = 6.2mph.

>10kmph faster in town could be the difference between killing someone or not hitting them at all. I think of the difference between hitting someone and not hitting them as measured in distance, not speed.

  Speed determines time to stop including stopping distance and reaction time. For every second of reaction time per 10kmph you add about 4 meters of distance travelled before you even hit the brakes. So best case if you aren't looking at your HVAC, at 50kmph you will start the stopping process in about 28 meters, and at 60kmph it will be 33.3m and take longer to stop once you hit the pegs. Doesn't sound like heaps but that is actually your margin for error, just 4m. If something jumps out in front of you at 28 meters away, at 50 you will have had 4 meters to stop, which modern cars can do, and at 60 you will hit them at the full 60kmph. The Australian government has some great road safety clips on the subject, I might try and find them.
