I know that you always here that speed causes many accidents but what they don't tell you is that most accidents where speed was partially at fault does NOT mean that going over the speed limit actually occurred.
Lets say you are on a freeway and a big SUV/Semi/Whatever is in front of you. You come around a bend and low and behold the traffic is stopped, but it takes you a second longer to see it because of the big SUV in front of you. The speed limit is 65 and you are actually only going 60, you try to break but you impact the vehicle in front of you at about 20 mph. Many freeway accidents are rear ends.
The speed minimum on a freeway is 45 MPH.
The reason speed was a factor in this accident is because cars were actually going below the speed minimum. However, all you will here is that the driver was going to fast. Well, they were going 5 miles per hour under the speed limit.
Now accidents in cities usually occur at intersections. You hear that the driver was going to fast as they entered the intersection, but what you don't hear is that the speed limit was 30 mph and the driver was going 42 mph.
Sorry, but a governor is not going to prevent the speeder from going 42 mph in a 30 mph. Even if, as the article says, it reads the speed limit sign. Well, in the city there is not a speed limit sign everywhere. I can often enter a road and go a mile before seeing a speed limit sign.
So the governor is only going to prevent accidents that occur on freeways by drivers going over the posted freeway speed limit. Well, go do your research and you will find those type of accidents are some of the least common.
So no, governors on cars will probably not reduce hardly accidents.
In fact, driving 80 mph has proven to keep people awake on long freeway drives, so what you are likely to see, at a controlled 60 mph speed, is a lot more drousy drivers falling asleep.
What will happen when the number of accidents by drowsy drivers increase?
