> the cost is unsustainable

While I am a huge proponent of public transportation and thus think this study is stupid on the face of it, in favor of actually having buses, we should, and in fact do, subsidize transportation. Oil is heavily subsidized, as are the roads themselves. IMO we should also subsidize public transportation to a much larger degree. That Uber/Lyft is able to be a transportation option if subsidized then, doesn't indight it on the face of it for me. Much as I hate to admit it, that is. I also hate to admit that there are times when Uber/Lyft are actually the superior option, and it makes sense to subsidize. Eg if you're not critically injured, an Uber/Lyft to the hospital ER works out better.
