This reminds me of the spark plug ceramic demos. Little ceramic tip on a spark plug (isolated from the rest of the plug) make an effective car window smashing projectile. No idea if it would work from inside the car / if you could get enough speed on it sitting right next to the window!

Technically it's not the tip of a spark plug, but a shard of the ceramic insulator when shattered- https://en.wikipedia.org/wiki/Ninja_rocks

So they crush a spark plug to get the "rocks"? How?
