This "car-tinkering app" is used as a glorified GameShark for deleting factory emissions controls, I don't feel sorry for anyone who uses this to roll coal or whatever. Instead of investigating everyone on the list of users of this app, should the government instead ban diesel engines knowing their emissions controls software will be defeated? Should environmental regulations be relaxed? What is really the solution here?
They want testimonies to use against the app. The solution they're trying to pursue is to outlaw the app, not investigate its users.
Periodic vehicle inspection for emissions and safety compliance. Many jurisdictions already have this for gas engine emissions, a handful of states already have safety inspections. Done right, it can be low burden and low cost, and basically put an end to Def deletion. Done poorly it's grift to the shops that do the inspections, and an economically external annoyance to vehicle owners, and unnecessarily limits the ability of people to tinker with their own vehicles.
federal and state governments buy and operate diesel vehicles without emissions controls because of how bad they are in critical situations. rules for thee but not for me.
Or, I don't know, enforce current laws on the books and have cops do their job?
I've watched traffic code enforcement drop to essentially non-existent numbers largely because apathetical agencies and "officer safety" concerns.
I'd rather they go after people actively rolling coal instead of violating the rights of thousands of Americans like me.
