Tesla had first to market advantage as well as autopilot to put them at the front of the market, but these companies don't have any of those advantages.
How are they going to compete in the market against Tesla, Ford, VW, GM, Daimler and other big auto companies who are going to be flooding the market with their EV over the next years and out scaling them do to having massive amount of cash, infrastructure, and supply chains already built. While Rivian will be stuck spending massive amount of cash to build infrastructure and supply chains all while playing catch up.
Ford is already outselling Rivian trucks and SUV with their Lighting, and Mach-E models all while being a profitable company.
Rivian is already valued at over half the value of Ford. Where do investors see the growth?
