From a purely investment point of view, why would anyone invest in Lyft over Uber? Lyft has a smaller footprint and only operates in the US (except Toronto).

well, marketshare (a percent value) is by definition a zero-sum metric. however, what you mean to say, that every new customer of lyft is a customer less for uber, is false. there is no network effect, like social networks or marketplaces. new customers for uber may also be customers of lyft, and in a true rising tide, and one company may prime the market for the other.
