generally, I'm not in favor of too many new laws, but, those recaps for trucks should all have 1 or 2 RFID chips inside them, the numbers associated with the end-user, and local communities and folks that have damage from them could then trace the last user. (kinda like those pet tags) The road cleaning crews could send in a bill for everyone they pick up, and insurance companies could get some payback from the trucking company if one of their clients' cars was damaged by a chunk. I realize it wouldn't be a perfect system, but, there aren't any perfect systems. It may be enough incentive to improve the recaps and keep trucks from driving on marginal recapped tires.
