I'm completely against 'buzzing' cyclists or runners....
soooo, are you retracting your earlier comment?
This one!!!!??? What are you going on about here? What comment?
starting today i am honking at any idiot running in the road when a sidewalk is available.
What does that have to do with following/harassing/buzzing people, all of which are illegal actions?
Seriously, WTF are you trying to get at here?

Forget it. Everyone reading this thread sees the ridiculous back peddling you have done.
You will obviously never admit it, with the lack of testicles and all.
I know, you know it, everyone knows it. No need to continue.

Be careful, he may get in fear of his life and bust a cap in your ass....lol.
Based on what?
Look, you throw a rock at someone and that is assault with a deadly weapon and could certainly get you legally killed in many states. You might want to brush up on Florida's self defense laws before you get yourself killed.
I am well aware of esp. Florida's law. Good luck with that gun of your's and your belief that harassing a runner that approaches you warrants the use of lethal force.
You really should look up the definition of harassment.
If I don't are you going to shoot me....lol
Well I'd hate for you to violently approach me for honking at your dumbass and you end up dead over it. It really is for your benefit, as you clearly have some anger issues.
Like having to blow your horn at pedestrians?
Trust me, it doesn't make me angry at all.... I point at them and laugh as I drive by. If anything it probably makes my day a little bit better, I love forcing idiots to be aware of what they're doing.
Alright here we go then.
I found some calculations on the internet.
Furthermore, here is a nytimes article where a researcher says there is no evidence of there being any difference in injury rates from surface hardness.
And here's a research paper that says there is no significant effect of running on different surfaces.
And to add some anecdotal evidence: I run on asphalt, concrete, and a treadmill. My worst injury (stress fractures) happened over a winter when I ran exclusively on the treadmill. All of my other injuries have been either pulled muscles or foot injuries from stepping on rocks etc.
I found that same thread. Many of the calculations were dismissed in that very thread. Also, the guy who did them is a CS major. I forwarded it to my bro in law who, like I said before, is a civil engineer with a P.E. in structural engineering and a specialty in concrete construction. I was initially convinced by the numbers you posted until I had a conversation with an actual engineer in the field. Also, you are ignoring all of the actual measurements I took that refute the horribly wrong conclusions in your quoted data. Get this through your head - asphalt is 15x softer than concrete. His E.I. numbers are slightly different than what would be considered typical, but still close enough.
The articles are interesting. I don't see enough data to really draw any kind of conclusions, though. My objective in taking part in this thread is to show that there's a non-trivial difference between the two surfaces. How it affects your body is unknown to me, but it makes sense that softer (not too soft, though) would be better in some capacity. I'm not trying to argue that point, though.

The calculations weren't dismissed in the thread by anything beyond a handwaving of "I don't believe it". No one posted anything really credible.
I'm not 100% sure they are correct, but they do support my premise that while asphalt is significantly softer than concrete, asphalt plus a running shoe is not noticeably softer than concrete plus a running shoe in any way that would make a difference.
The other papers I've posted links to also support this.
Asphalt is 15x softer than concrete, but your running shoe is 1000x softer than asphalt and 10000x softer than concrete.
Let's play that out for a minute.
Asphalt - relatively soft, injury free*
Concrete - 15x harder than asphalt, causes noticeable pain/injuries
Steel - 7x harder than concrete, ?
Diamond - 5x harder than steel, 35x harder than concrete, ?
If concrete is so much worse than asphalt, would running on steel for 1 mile cause stress fractures? Running on diamond is insta-death?
The shoe takes virtually all of the strain/stress, anything remaining is inconsequential and amounts to a few steps difference over a mile.
How about getting off your ass, buy a pair of shoes and do some running on concrete and asphalt at around 3-5 miles per day and get back to us after a few months of it.
Oh and be careful SA doesn't pull out his .44 magnum and blow your ass away for sharing his road.
Absolutely the roads are smoother with less obstructions than sidewalks.
Although I prefer to run on a track. Even more sure layout.
