Your comment raises an important concern - safety and the distribution of spheres of interest. I must admit I hadn't considered these factors when writing the article. In my mind, I pictured a calm European city like Barcelona. I would be thrilled if the first city to implement this taxi-bus system was Barcelona, and I see Los Angeles, with its upcoming Olympics, as the second most promising.
Of course, the taxi-bus system will not solve the safety problem on its own, but I believe it won't be any less safe than any other form of public transport. Therefore, all other things being equal (as we mathematicians say), the taxi-bus system should be better.
