Regular cars have a lot of OS'es in them that are not QNX. I'd say OSEK derived OS'es are much more common than QNX. And I believe there is quite a bit of space for alternatives.
You’re right, they do have lots of OSes. But most of them are for lower-ASIL elements where the functional safety and SOTIF requirements are less strict. I’d be very surprised if there was quite as much diversity at ASIL D.
Edit: Usually good form to point out your affiliation when you're commenting on your own company's announcements. Unless I'm very much mistaken, RadVl sounds a lot like a portmanteau of Vlad Radulescu, FSM at OxidOS. It's a great looking product, don't get me wrong!
There are 2 ASIL-D OSEK implementations off the top of my head, Tasking, the EB one ( I think they actually have _2_ variants here, the normal one and a microkernel) and I'm sure there are others, these being just the ones I saw on projects I worked on before Oxidos.
I'm sure Vector has one as well.
Edit: You are right, that was poor form, I added the disclaimer.
