    The magnitude of the friction on the tires is still dependent on the load so would be hard to say without crunching the numbers… but ya I agree with u, its probably much less impressive than it appears, which is all that really matters w demos like this

      There was also a demo of a cyberpunk pulling a train. I think it was practical engineering on YouTube. He then goes on to explain how little it actually takes to break fiction, why there’s slack so you only pull one cart in the beginning and get inertia to do a lot of the work. It basically called out the stupid demo, and went on to show why trains are awesome.
