Huh? What? No. That's not where the valuation came from. To be fair to Uber, they created a new type of market for which there was an immense demand for. Their self-driving initiatives were a moonshot and maybe got some people excited and therefore invested in Uber (see Tesla/Musk), but not quite the same as saying it drove their valuation.
>Tesla, ... were priced as if self driving cars are almost here.
Tesla was/is a hype stock based on the personality cult of Elon Musk that stemmed from being first-to-market with EVs. The valuation wasn't really driven by whether or not Tesla cars are self-driving.
