  • I used to love that sub. Then it started to be about legal responsibilities instead of morality… From there it really turned into a dumpster fire

    The only time I’ve ever been banned on a forum because although I said the woman had the right to do what she did and the guy was clearly in the wrong, she needlessly escalated when empathy would’ve led to a better result for everyone

    No explanation, just a temp ban. For advocating empathy and third path conflict resolution



  • But then, why would they be more stable when moving, even without a rider? If the steering is tight enough, you can push a bike to someone a good distance away. You can do it with a scooter too, although it’s a lot harder.

    You can also look at a motorcycle. Their mass is far greater than a human’s, a person could never manage that. Those little RC motorcycles are the same, they don’t need some crazy balancing system to mimic humans, they just need to stay upright enough to get some speed going, then they balance themselves.

    It’s the same with a wheel - the speed makes it stay upright, they can balance on the tiniest edge so long as they’re moving

    It’s not a gyroscopic effect either, though that’s present. It’s a balance between rotation speed and the friction with the ground - the object as a whole has momentum, the rotation has momentum, and the contact with the ground balances the two. It’ll try to put it’s center of mass in line with these forces acting on it

    Add in a human, and they can shift the center of mass on the fly. The vehicle’s speed is still pushing you upright - get on a bike with some good speed, and you can lean very far into a turn and ease off to return upright. Way more than you could if it wasn’t moving
