I've never understood why some people insist that FSD means there can never ever be any crashes of any kind, otherwise it obiviously just doesn't work.
I use FSD 99% of the time now and it works 99% of the time I use it. When it doesn't work, it is always in an annoying, going-way-to-slow way. I've never experienced it crash into anything. I'm sure the experts here know better than me, I'm just a lowly customer, but from MY experience, it basically works all the time.
