    No it doesn't. It just means the traffic must slow down approaching the merge point.

    Your theory is not correct. There is a speed at which capacity is maximised. Below that capacity is reduced , but it's also reduced above it. The specific speed will vary from road to road. The way to find it is by observation, not math.

    https://en.wikipedia.org/wiki/...

    However it's a blind alley. An individual car cannot control the speed of the traffic as a whole, and it it tries to go as fast as possible as you are suggesting, that will actually slow down the traffic as a whole. The best heuristic any particular car can do to help the traffic flow is exactly what it says in TFA. Seek to make the distance between cars to the front and the back equal (subject to a maximum distance beyond which it doesn't matter any more.)

    Of course it's asking too much of human drivers to do this, monitoring the space behind at all times is expecting too much. But for automated cars it's a very sensible heuristic.

    That's standard, and legal behaviour in the UK too.

    It's not "an assumption" that all distances would be equal. It's a heuristic for each car, at any particular moment to seek to equalise the distance between the car in front and the car behind.

    If there's a merge of two similar roads, then of course the merge would happen. And after the merge the average distance would be halved.

    Speed and safe distance to other cars are not independant variables though. Generally speaking slower speeds allow more throughput of cars, because the distances between cars (wasted space) is lowered.

    In fact it's this dependancy that explains WHY congested traffic moves slower. The smaller distances between cars demand slower speeds.

    I guess you didn't read it. Your article is about Bitcoin mining. We know that's happening in Venezuela, that's what TFA is about. But it says nothing related to your claim that Venezuelans are using Bitcoin to buy groceries.

    What you are missing is that whilst Venezuela is worse for the rich people. It; better for the poor people. Not great, but it was worse when the capitalists were in control.

    Yes, they get the leadership they deserve. They keep voting socialist because the socialists make their lives better. They are not stupid, and you are not in a better position to say what they should vote.

    Unless the chargers are built on top of the mountain, the truck will have emptied more space in the battery on the way up the mountain than is needed to store regen electricity on the way down.

    Idiot. More ability to pull loads, more ability to accelerate when unloaded. The acceleration comes for free from the fact that the Tesla is specified to pull a full load up hill faster than a diesel. And because EVs naturally out acclerate internal combustion engines.

    Acceleration will not have been a major design goal. Just a happy side effect.
