After watching what Tesla is doing, they have chosen not to invest those resources even though if they did, they would beat Tesla at its own game quite easily because they eclipse it both in capital and experience.
Either their analysts are wrong and failing to see a winning strategy here, or there is no winning strategy. One of these two statements must be true. I've put my money on option #2, but I'm aware that large competitors aren't idiots and there is a risk here.
Elon Musk has also publicly stated that he wants the other big players to compete with Tesla. He doesn't actually care if Tesla is ever profitable or not, he just wants to force the world to transition off fossil fuels by dispelling the myths sown by the oil industry with concrete examples of success. It is stupid to ignore Musk's stance on this matter as an investor.
