Everyone, carmakers as well, are watching silicon valley software companies making huge bank from their software products. The other car manufacturers also want to get the big score, and will try and do it themselves, by acquiring some part time or small potatoes startup doing FSD like stuff, and try and direct and grow it in such a way that they can score big too. They will rationalize this by saying if elon can do it anyone can, and will put the twitter example as proof (remember the analogy does not have to be accurate but enough). They will make a powerpoint presentation, and get huge VC funding, because VC looking for the next big score, and wa-la, the other manufacturers get the big score without doing anything meaningful. No one cares about safety and a safer car is going to mean less money for car manufacturers and automobile insurance companies.
