Why does the bottom not move 😭

Do people genuinely not understand how treaded vehicles work????

The bottom is gripping until the rest of them catch up.

We're you expecting it to twerk too?

tracked vehicles are essentially trains that lay their own tracks, that's why, that was the whole idea

...In the same way the bottom of the tread of a tire doesn't move... If it moves (slips from the ground) congrats, you're doing a burnout.

The invention of caterpillar track was the idea of building a locomotive that laid it's own rails, so it could go anywhere with the same stability of a train.

Haven’t thought about smth like this since elementary but I’m glad I’m able to see it

As someone who works construction I have no idea why

Weight+friction=movement

Are you fucking stupid?
