Sorry to keep sounding like a pedantic old buffer, but it ain't speed that's the real problem.
Best wishes all,

But people don't stop hitting things, it's merely a damage limitation exercise in reducing both the incidence & the severity.
One of the key factors in avoiding things is having time to do it. Speed works against you there & as we've said if you can't avoid that, the velocity along with mass will provide the energy to make it a whole lot worse.
No I know people don't stop hitting things, but they don't hit them very often - in fact on average it's extremely rare - so let's put some more effort into making it rarer still.
As for speed working against us, it's merely a matter of ensuring that we don't have excessive speed to the extent of having insufficient time to take successful avoiding action, or whatever.
I'm not disputing the physics of all this, there's no getting away from the velocity x mass business, and the fact that the more of those two you have, the bigger the thump, and the more likely it is that people will get hurt.
At the end of the day living is a dangerous activity, and we should accept that sh*t happens from time to time. I hope you will not feel that I'm taking an unduly cavalier attitude to safety, but I believe that with the right sort of approach we can make the impacts a sufficiently rare event to be acceptable IMHO. Are we getting too risk averse, I wonder? I think we are, and it appears I'm not alone in that view.
Best wishes all,
Dave.
