That shweeb thing must be one of the most stupid things I've seen. On the other hand, giving Khan Academy money alone is worth every penny given to him for the great work he has done.
I hadn't heard of shweeb, but after a look at the website, it does indeed sound like a remarkably unworkable idea. Still, maybe there's some kind of possible idea for human-powered public transportation that doesn't look like a haven for system-destroying minor breakdowns and upskirt photographers.
There's also a lesson in there somewhere about how if you have an idea which seems silly, you should avoid also giving it a silly name.
I think you hit the nail on the head - it really just sounds unworkable. Just getting civic approval seems unsurmountable, the system seems frail (breakdowns, capacity, misuse) and all it is going to take is one person to have a serious medical issue with no chance of early responders being able to address the issue for this to get shutdown.
