Usually an optimist and a believer in Tesla's ability to execute - but I've finally found something about which to be skeptical - the business viaability of a Tesla-exclusive rideshare network ie the "Tesla Network." Personally I think this is a harder problem than full autonomy because it's a critical mass problem. As a ride share user, I do not care whether a human is driving or not - I just want to be picked up and picked up NOW. Uber delivers that experience in most places I go in California - but it does so by leveraging lots of humans driving lots of inexpensive cars from many manufacturers. It's hard for me to imagine Tesla getting a critical mass of rideshare participants any time in the next few years so that the service becomes practical for users - and thus popular enough to at least break even. On the other hand I could be wrong. If the cars exist anyway sitting around in customer garages, all Tesla has to do is build a software platform and take a slice of the revenue. But again on the other hand if rideshare profits were that easy Uber and Lyft would both be relaxing. Uber claims to be profitable in the U.S. but Lyft is still losing money - and both are far larger than a Tesla network would be for years.
