> In a sufficiently dense area, there is clearly a market for app-summoned taxis (for various values of who owns/maintains/pays for said cab) Oh well. For sure, but it's a pretty vague statement, isn't it? We're not talking about some modest value that can keep some small company running; we're talking about $75 billion value. I'm sure that not one, but many small companies can thrive providing local services to taxi drivers collecting and dispatching hails. But that's a far cry from that to a single global company valued at almost a hundred billion dollars.
