The obvious use case is to avoid a collision!
Single use is perfectly fine for that purpose. No one complains that airbags are single use.

I'd say the best way to avoid collisions at scale is already on the road and its cars with sensors and computers, if we weren't living in a pre-cyberpunk dystopia I would gladly have them coordinate to achieve that
The "air rockets" could probably also be used as hard emergency brakes.
