"Sub solen nihil novi este"<p>I've been backpacking around SE Asia for a few months now, and this sort of system has been active on an ad hoc basis for years in Chiang Mai, Thailand. There, it's expected that "red cars" (seemingly the only active taxis), will pick up other passengers.<p>They'll stop for passengers flagging them down, and check location before issuing a quote, if in fact they're on the way. While this made traveling really cheap, there were times where a 10-minute trip stretched into over half an hour. I'm interested to see whether these services will customize allowable wait times to the individual, or whether all ride-sharers have roughly the same tolerance for delays.<p>But, to say that any one company copied another in this case is a pretty stupid argument to make. I asked myself this question the first time I rode with Uber, and I'm sure many of you have as well. I would imagine that any good PM would've thoroughly investigated it; it's pretty obvious.
