I tend to dislike them because of their past but I'll defend with a thought about their roadmap. With their current business model, I don't think they have it in the bag. They don't have much that other ride shares don't. But I think that if they had the infrastructure built out to support their current model for the whole country, they would be the only company capable of being the software side of autonomous vehicles. Or, at least, the best positioned company to win that contract. I think that transportation itself is big enough to warrant such a big valuation. So I think their competitive advantage will be built over time and, right now, it's not anything sustainable by replacing taxis. Of course, once someone wins the race, maybe we won't need anymore clones since the cost/transaction will reach a good equilibrium for everyone. Then they can build a different type of sustainable competitive advantage.
