If this comment's source is correct:

Among pedestrian fatality and severe injury crashes: LT crashes outnumber RT crashes 3 to 1

Then if you have to make three right turns to make up for a left turn... do you come out the same? I am not confident enough in my command of statistics to determine whether the relationship is that simple.

Either I don't understand what you mean by "fill up," or what you mean by "24/7," or you're just trolling and I am falling for it.

I took "fill up" (and previously "peak capacity") to mean "the most cars that can safely fit on this stretch of road simultaneously, while going the speed limit." I also took "24/7" to mean "all the time."

If you wait long enough without widening the freeway, you will not see peak capacity maintained indefinitely. People aren't going to "fill up" the freeway at times when they don't have a reason to be on it.

I agree entirely that the equilibrium point will have nonzero amount of traffic congestion at some times. I assert that it is less than half the time, though.

Your first sentence is rubbish. Rhetorical questions only work when the answer is in favor of your claim. A demand curve doesn't "show a way" to keep traffic flow constant any more than it "shows a way" to solve any other perennial economics problem.

One could certainly under some conditions manipulate demand into a constant flow, but those are merely thought experiments. There are toll roads that attempt to regulate their price based on the traffic in them, but they still can't spread traffic out constantly. You aren't going to pay people vast sums to incentivise driving in the middle of the night to keep your traffic flow constant. One could also reduce the lanes to zero. You'd have a constant flow of no cars, but that's also unhelpful.

Now that I've knocked down some straw men, do you have something interesting to say?

It is indeed a small state, and because of that, the area taken up by people who live within the environs of Baltimore and DC is a sizable fraction of the state's entire land area. It's not as high a fraction as New Jersey or Rhode Island, but it's not in the same league as Virginia or Pennsylvania.

I still don't know what you mean by "overall sparsely populated." I wouldn't be surprised if you could come up with some formula to divide New England and the Mid-Atlantic into "MA, CT, NJ, RI" and "NY, MD, VA, PA." I do, however, assert that any such formula would be contrived.

And now I feel silly for arguing a bit of worthless pedantry on the internet

If any highway anywhere moves half of its peak capacity in a day, the transportation engineer responsible for it should be fired.

They're not intended to move a constant vehicle flow. Rush hour is not an arbitrary phenomenon. It's come about because we structure our lives around visibility of the giant ball of fusing gas we orbit.

This is untrue. At least 80% of actual legislation introduced by congressmen is written by the non-partisan House Office of Legislative Counsel. While I can believe that more legislation is written by interested non-government entities than ever before, it is not even close to a majority.

Most bills are drafted when a congressman gets an idea (which could come from industry, sure) and asks HOLC to write him/her legislation that actually implements her/his idea.

I am not under the impression that the HOLC is well-known.
