As the article points out, it remains to be seen if this is for self-driving use or in-cabin. Europe requires interior intrusion sensors in passenger vehicles, which afaik can be radar-based. There are also possibilities for fine-tuning of airbag deployment based on occupant size and shape which could be determined by a radar.

What do interior intrusion sensors in cars accomplish? I’ve not found anything about this online nor that Europe requires this.

Sets off the alarm (an in a Tesla, gives you a phone notification) whenever a window is broken, or something enters the vehicle while it is locked. In an American car (at least last time I checked a few years ago), the alarm only goes off if you use an interior handle while the car is locked.
