CAFE Standards: Going at It the Wrong Way?

Many of you probably know about the fight over CAFE standards in automobiles. CAFE stands for Corporate Average Fuel Economy, and basically it's the average fuel economy rating in miles per gallon for all the cars in a company's lineup. A great explanation of it can be found here.

If you read this, you can see that the standards are sort of flawed - they only count cars up to a certain weight, which most certainly doesn't account for ALL the cars on the road, only the more fuel-efficient smaller models. SUVs, trucks, etc. all get ignored.

But that's neither here nor there for the purposes of this post. My thought is this: instead of trying to govern the mileage of various car companies, but not do anything to improve road safety, why not kill two birds with one stone by installing some sort of mechanism that would set a maximum speed at which motorized vehicles can travel?

This would do a couple of things: 1) people wouldn't be able to waste gas by going too fast, and 2) roads would be safer because people would be going at a more reasonable speed.

I know that many people will say that this is fascist rubbish, but is it really? I would say that the greater evil is continuing to allow for (and even subsidize) a road system that allows 43,000 deaths per year for the sake of going faster.

Obviously, emergency vehicles would be allowed to go faster, but if no one else could go faster then you wouldn't have many of the issues that emergency vehicles have when trying to get to the scene of an incident quickly.

Anyway, it's a thought, what do you think?
