I sometimes barbecue on my sidewalk where I live. I assume it's legal (I'm taking a risk), or at least it's tolerated by my neighbors and police officers walking by. This is probably because it's only me, I'm not causing any trouble, I share, and clean up. I assume if everyone started BBQing (or someone started complaining about me) the local government would need to look into it and figure something out: Is he breaking a law? Do we need a law? A guideline? A public BBQ? Etc. At this point common sense and public debate can start. It'd be silly for me to run for mayor or start a statewide proposition for sidewalk BBQing when I just want some hot dogs.
Tech workers needed to get from their houses to their office, but there was no existing convenient way of doing this. So they bought a bus. Then more. Others followed. Now there are some questions arising and society (read: government) needs to get involved. How many busses are allowed? Can they use bus stops? Should we charge them? A little for usage or a lot for subsidizing other's transport? Should Muni buy new comfy buses with wifi and run new routes to mountain view? Can they do that or does the other transit authority have rules against that? Would people ride this, or would it be a waste of money?
Perfectly reasonable questions, which should be debated and negotiated. But not from day one.
But let's be honest: it's not about the busses. It's about inequality.
