Shit you may have nerd sniped me.

Could a blimp be sailed like a boat? I don't think so, it's a different physics problem. A sailboat is both hydrodynamic and aerodynamic, it's touching water and air, a blimp is only touching air. A sailboat can sail into a quartering headwind by turning the yards so they form an airfoil creating lift like an airplane wing in a mostrly forward direction, and it keeps from sliding sideways by the mass of the water interacting with the hull. A blimp with masts wouldn't do that, the wind will act on the envelope to just push it downwind, the sails might be able to drive it slightly forward so it goes slightly off to the side of downwind?

Also, to keep it from being blown over you'd have to hang the masts below the airship rather than above like a boat. Bouyancy is much more precious on an airship than a boat because air is a much bigger pain in the ass to be lighter than, so a deep keel full of lead like a sailboat ain't gonna cut it. Putting the masts on top would be too easy to blow over, if you hung them from below crosswinds might cause a rolling moment but it wouldn't roll all the way over.

Damn I wish they were still making Mythbusters. "Could an airship with sails sail into a quartering headwind? Or in any direction but downwind?"

That girl had a crab ran on her last party.

Hey there 👋, I know you mean well by that comment, like I get it, I do. ☺️ But I just wanted to let you know:

THERE HAVE BEEN ZERO STUDIES DONE ON THE SAFETY OF CRAB TRAINS.

ZERO.

But despite that, they are gaining widespread support, and now even people like yourself are calling them "optimal."

Listen: Someone I know lost an arm in the pincer mechanism of one of these trains. More work needs to be done before we can consider them safe, nevermind "optimal". Don't buy into the techbro BS.

Friends don't let friends crab train.

As a tf2 player. A crab train is majestic.

Cars in a station?

IDK why but I actually thought the title was this pun when I first read it. It was only after reading your comment that I realized that OP didn't actually cash in on the joke (skill issue, smh).

Nice pun, I think you railed it

Even in bike racing the optimal form ends being to become a train. A peloton is just a train made up of bikes.

There's likely some cases of convergent evolution, but I'm not sure this is settled for all trees.

I'd suspect that at least some trees with last common ancestors that are shrubs have re-enabled genes that enable the tree phenotype rather than independently evolving the tree phenotype.

But still really cool (and maybe turns on exactly how much evolution your consider needs to happen before it's convergent evolution.)

Okay so now we are looking at some kind of tree-crab-train as the crown of creation, am I understanding this correctly?

That seems unfairly obvious, but I certainly didn't consider it before.

https://en.wikipedia.org/wiki/Intermodal_container this is kinda the same idea.. same container can be transferred from ship to rail to truck

A less efficient train, because it has a bunch of small engines and batteries instead of one big one

Yes. That is the point. Trains are optimal.

Inter-vehicle cooperation and autonomy makes highways act like trains, yes, with a bunch of unnecessary steps

They do though?
