Not sure about self-driving cars. I work in robotics, and there are a few modules that need to hit hard real-time deadlines. You wouldn't use GC languages for those, but there are a LOT of other parts that don't, and you can get a BIG win by writing those in a more concise language.
And avionics/aerospace.
And self-driving cars. And medical equipment.
etc, etc. You can list lots of fields for which this is unacceptable, and they are a lot of the really interesting fields.
