The thing that pisses me off the most about things like this is the fact, I say again fact, that speed is far too often blamed for accidents where the speed was not the major factor, but the driver's lack of skill or more likely common sense.
By this I mean people who follow too closely, pass when they shouldn't, or are reaching for their quadruple latte / fiddling with their iPod. Watch a couple episodes of "Seconds Before Disaster" and you see that very few accidents of any kind are caused by simply one factor. In nearly any given accident you have several factors at play and usually one of them is human error.
For example a multiple car pile-up on a highway in the US or Canada. When the injured are taken to the hospital and the cars are cleaned off the raod the tickets that are issued are for speeding or failure to reduce speed to avoid an accident. this stems from the 50's when the number of cars on the road multiplied by a huge factor. Thus the rate of fatalities from car accidents increased. Federal studies that ran on into the 60's and 70's concluded speed was the major factor at play. Becuase of that and other factors including the oil crisis led to a federally mandated reduction of speed limits on our highways and biways. Even after the speed limits were raised in the 80's and then turned over to the states' judgments in the 90's our country and to some extent Canada has remained fixated on the "speed kills" philosophy.
Now, don't get me wrong. Speeding, especially in extremes, does make driving more dangerous. Stopping distances are greatly increased and time to react is reduced for, in most cases, very limited decreases of travel time from place to place. But, the judgement and skill of the driver is the greatly overlooked factor.
You can exceed the speed limit and still be a safe driver. You have to increase your following distances, understand the amount of time it will take to slow your vehicle, be aware of road conditions, pay attention to traffic patterns and for god's sake pay attention. Speeding, riding someone's ass and searching for your favorite track on the iPod or dialing home is inherently more dangerous (and probably the cause of more accidents) than is speeding by itself.
For those who argue this, do a google search and compare the fatality rates of the US vs. Germany per capita. It's amazing. Germans drive in traffic at speeds that would turn most of us white. I've been there and I wouldn't want to drive on the Autobahn. However, they lose far fewer people every year than we do in car accidents. Why? Because driving is serious shizer over there. In fact up until recently very few German cars (real ones, not the ones we import) had cup holders. They know how to drive at speed and that's why less people die there every year. Their cops ticket those who follow too closely or attempt to drive in the passing lane. Speeding is not their big priority.
Anyhow, sorry if I veered too far off topic. This is just one of my rants.
