Take it a step further.

What if you discover a crack less than 1cm in width with this fancy robot or my GoPro on an RC car?

Are you really going to fix it? How? Is it worth it? Or would you just wait until the crack gets big enough that it would be easily visible on a camera anyway?

Probably use the information for modeling future maintenance/replacement schedules and such. Less "we see a crack, let's fix it" and more like "we're seeing X new cracks a week, let's bump up the maintenance of this sector by Y months" or whatever.

Also if you spot a small crack you note the plcement it and keep checking it regularly to see if it is getting bigger.
