Not a Tesla fanboy (I'm turning mine in for a Rivian), but the OP wasn't saying this, not sure how you got that conclusion. They are saying for a car company they are (1) way behind and (2) any investments they are making won't reach fruition for years, nor likely make a dent in the industry.
Outside of MB and the Chinese EVs, the design of Tesla motors is far superior. Their build quality and finishing is awful however - something the traditional players do really well.
