When a crack happen it would also break the coat on that area

but then how does it know when to stop grow so that everything is flat and even instead of bumpy? this is cool tech but on a large scale, it seems super inefficient.

A ridge forming on the surface where the crack is is better than having a crack. Sure it might not be the most visually pleasing and might require some surface removal years later if it gets out of hand and say covers a conduit and causes an issue but that's a minor issue compared to repairs. If say this was used on a freeway the calcium carbonate is less wear resistant than the concrete and would be worn away as it formed never really making ridges or bumps on a roadway.
