In regard the Texas speed limit: Did you bother to check which highways would be eligible for the 85 mph limit and what their current accident rate is? How many head-on collisions occur on those highways now? I haven't looked these up, but that's the point - you didn't either, and it's disappointing to see you have the knee-jerk "speed bad!" reaction. If speed is so bad, then why don't we just lower the speed limit to 45 mph on highways? The answer there is that we have decided that the costs of slower travel outweigh the cost savings of slower travel. Who are you to say that this isn't a good tradeoff? And no, I don't live in Texas, but I've driven through it before, and am sympathetic with the desire to drive faster on those wide-open spaces that cover so much of the state.

Dude, take a chill pill and check your high dudgeon at the door. Nowhere in my very brief synopsis did I take a stand either way with regard to the speed limit. I merely linked to two blog posts by a physics professor who'd done the math for both collisions and mileage impact of such a decision; And urged Texans to read it so they're making an informed decision. I didn't tell them what they SHOULD decide.

Some people. Sheesh.

Dudette, you linked to two studies that only analyze very small portions of the effect of the 85-mph limit, both negative, and then have the gall to say you didn't take a stand either way. At the very least you could have said that gas mileage and the effects of a head-on collision are only two of many factors involved in whether speed limits make sense. A statement like "terrific one-two physics punch" doesn't seem impartial, it seems to imply something like "take THAT, Texas!"

At least you got a comment, right?

The Einstein Pedometer link seems to be broken. I get a 404. (Not that I plan to get one; first I would need an iPod.)

Several intriguing articles in the list, which I now have open in tabs and will read shortly.

Sorry, you're projecting, plain and simple. If you have an issue with Dot Physics' analysis, leave your snarky comment at Dot Physics. I was simply pointing to an informative math-y link. I take no position on whether the 85 MPH speed limit is good or bad. Could be either. Depends on what's important to you. But knowing the math behind it and educating yourself by reading the Dot Physics posts is the way to make a solid informed choice.
