I don't have any sources to back this up but I don't think that worries Musk. I don't think he's actually overly concerned about Tesla succeeding at self driving cars, or electric cars. Musk wants the self driving car industry to be better. He needs those technologies to be significantly better for his interplanetary ambitions to be realised. The solar roof, the power bank, all of the other endeavours he is engaged in are all intended to catalyse the industries that he's rattling the cage of. He'll need them on Mars and they're not good enough at the moment. Ford winning at self driving cars is a good result for Musk.
