Mildly Interesting

"Okay, I just got this great new idea. You know how freight by truck is so much more expensive than by ship? I think I figured out a way to get the costs down and apply it not just to freight, but transit too. I just saw a YouTube video on physics. We need to reduce the rolling resistance, for starters. I know what you're thinking. You're thinking hard, smooth wheels would slide all over a road of the same material. However, I took one of my private jets to lunch yesterday and took a walk on the Via Appia Antica. It has these cool little grooves carved by centuries of wagon use. They would even help guide the carts! Now you might say that still leaves the problem of having a big, expensive road. I got you covered. We take the inverse of that arrangement. Instead of recessed, curved groves and flat wheels, we use raised, flat strips (or rails, if you will); curved, convex wheels and ditch the rest of the road entirely. We'll save billions on this road made of rails and that's just a start! What's the most expensive part of the truck? The tractor, that's right! So now that our rolling resistance is down by a lot we can pull more trailers. I call them "Carry-All Retention Sytems" or "CARS" for short. Also, the harder surfaces means we can use bigger, more powerful engines. We could have a tractor trailer arrangement longer than several trucks, kinda like how a bridal train is sometimes longer than the dress itself."

"Do you hear yourself? Rail, Road, cars, train."

"Uh, oh. Did I just invent trains again?"

"Yeah, it's like the third time you've done it. Unless you can come up with something that'll add value to trains, I think we'd better move on."

"Umm...AI? We put an AI on the trains, in the trains or maybe in the control centers?"

"Ugh, goddammit! I'll assemble the investors."
