I'm not usually one to call for "nanny" laws or regulations but those types of situations are just the perfect excuse for having filters trapped in a captive device that can only be opened by licensed mechanics. Sure there would likely end up being a grey or black market of third party workaround devices. It happens in any situation with regulations. Its just ridiculous that the knuckleheads are able to make and keep enough money to spend on some of the more ridiculous clown monster trucks on public roads.
