I'm not sure if it's legal or not (or even whose jurisdiction it falls under), but I'd caution you that it's probably a lot more difficult than you'd think to determine if it's legal. When it comes to transportation, there are all sorts of levels of regulation (highway boards, transportation safety boards, municipal and regional codes) than you would think, and all like to regulate slightly different issues, and aren't very accessible to the average layperson. The other thing I'd caution you about when trying to monetize this is that the local bus companies will almost certainly come after you, and will have legal teams who are used to fighting the minutae of transport law - so don't be surprised if you find yourself having to lawyer up with some very specialized (and hence, expensive) counsel. As an example of both, here's ([1]) a story of a Canadian startup that was declared illegal by the Ontario Highway Transportation Board (a tribunal no Ontarian outside of the transportation sector has ever heard of) after the bus companies when after them. Seeing as it's in Canada that case shouldn't serve as a precedent, but does (as does the UberCab story) serve as an example about the challenges that come up when you try and disrupt something as established as the transpiration sector.
