I do not see the downsides here, what are you afraid of?

Think about it like this, Ford and BMW are collaborating to make better airbags , in future both companies customers will have more safety because of this so no BMW customers should be upset that the Ford ones also got better airbags. What about the other companies though? Some are making good enough airbags in their opinion, some are buying airbags from a third party that are also good enough.

I am wondering if there is a bit of Silicon Valley jelosy that this companies won't buy SV tech that includes the latest ML buzzwords, the thing is that cars had driver assist features before SV made the autopilot cool again.
