Sorry, but that doesn't prove that there are more accidents at 75 mph than at 55 mph. Or dispute that most fatalities occur below speeds of 45 mph.
 
And I'll bet if you ask a first responder whether he would prefer to respond to a 55 mph wreck or 25 mph wreck, he would prefer the latter.
 
So your example doesn't prove anything.

That study involved a very limited number of vehicles, and it was under conditions that were not necessarily duplicative of those on American interstates. Relying on junk research is never a good idea.
 
It doesn't even support that one should drive the speed limit. Note this sentence:
 
Some authors have noted that the increased risk from driving at speeds 10-20% above the average for the road is similar to the increased risk from driving at the drink drive limits in the two countries to which the references relate (i.e. a BAC of 0.05 and 0.08). (emphasis added).
 
The speed "average for the road" is not necessarily the speed limit. It is usually higher, especially on limited access highways. So this study does not prove that driving above the speed limit increases danger.
 
It also contains these sentences that poke a major hole in your claims:
 
If on a particular road, the speed variance is high, this will result in less predictability, more encounters, more overtaking manoeuvres, etc. (emphasis added) Therefore, when speed differences increase, the accident risk increases as well. Hence, a countermeasure that results in lower average speed, but in larger speed differences may not have the expected positive effect on road safety. But no reliable quantified relationship has been established for this linkage.
 
As has been shown repeatedly on this site, lowering speed limits only increases speed variance between the few who obey, and the majority who continue to drive at the speeds at which they feel comfortable. Given that photo radar will only slow people down in the vicinity of the cameras, it stands to reason that even MORE safety problems will be created by the majority of people braking to slow down for the cameras, and then speeding up once they are out of the camera's range.
 
Unless we are going to have law enforcement personnel regularly change the location of cameras, which is certainly a wise use of our highly paid police forces during difficult economic times.

Or, better yet, we give up this childish obsession with the majority of drivers who are exceeding arbitrary, underposted speed limits on limited access highways, and pour our energy into more productive pursuits that actually improve highway safety instead of raising revenue. That's the more informed approach.
 
I drove in Arizona this summer - most of the time at 80-85 mph on the rural interstate highways. And I was passed by a fair number of vehicles. It was perfectly safe. If you can't drive at those speeds, or get needlessly worked up about those who do, you should consider staying home, or moving to the city, where you can rely on mass transit.

Hold it there Mr Logical.
 
If you say, "And I'll bet if you ask a first responder whether he would prefer to respond to a 55 mph wreck or 25 mph wreck, he would prefer the latter."
 
Then right there you are admitting that he would rather attend a slower-crash wreck.
  
So your example proves mine it true. Thanks !!!!

"...I hear a lot of talk on these boards about "red herrings" whatever they are..."
 
Red herring is a false argument designed to confuse or distract from the real issue. Comes from an old practice of dragging a fish (a literal red herring) across a trail to confuse hunting dogs.
 
As a saying it's right up there with "let them eat cake".

"...Cars ought to have GPS systems which know the speed limits...Get everyone to understand that you are NEVER EVER going to get away with speeding..."
 
Along that line of thinking why don't we have the police just drag speeders out of their cars and shoot them on the spot. That would also get everyone to understand that they are NEVER EVER going to get away with speeding. It would cut down on repeat offenders too.
 
China did that with drug dealers in the good old days and it worked pretty well. Of course some of those bleeding hearts like the ACLU might complain in this country.

Goot Yob !!!
 
You respond with a red herring right after schooling me about what they are !!
 
Thanks !!!
 
I have declared a personal war on speeding and speeders. But with no authority to do anything about it in any way, all I can do is vent on these boards.
 
Go Photo Radar !!!

LMAO. My office mates are trying to figure out why i am laughing so hard. Love the suggestion.
 
Seriously though, I do agree that speed kills. Obviously a collision at higher speeds is worst than a collision lower speeds. That is basic physics and indisputable. The real issue is the driver. 99% of all accidents are driver error. Whether it's driving too fast, driving too fast for conditions, crossing the yellow line, inattentiveness, disregard for traffic signs/signals, not using your blinkers, drunk driving, etc.
 
I generally drive 10 mph over the speed limit on interstate highways (but stay at the the speed limit in town). If traffic is congested, I slow down and don't tailgate.

No, it proves how absurd your example is. And nothing you've said proves that people driving 75 mph have more accidents or higher fatalities. So your obsession with people driving 75+ mph on limited access highways is a waste of time. Maybe you don't like to drive that fast, but that's your personal problem that needs to be overcome, not proof that we need a very intrusive enforcement effort to address a "problem" that exists largely in your imagination.
 
Instead of "declaring a personal war on speeders," I'd suggest becoming better informed about really works to improve traffic safety, so that you don't come across as the internet equivalent of the old man squawking at the neighborhood children to "get off my lawn!"

grbeck says, "...your obsession with people driving 75+ mph on limited access highways is a waste of time."
 
I have no particular obsession against any speed. I drive in Texas where the limit is 80 mph, and I usually drive around 85 on that road.
 
It's EXCESSIVE speeding that I hate the most. People driving 15-25 over the limit.
 
You know, GRB, everything we do on this board is a "waste of time" but we still do it.
 
Have you declared a war on time wasting?
 
And unless I have shifted to another dimension, speeding is still an epidemic in this country and which is being now addressed by Photo Radar.
 
Go Photo Radar !!! $157 a pop !!!! Pay up, you Evil-Doers !!!!
