First of all, anyone who "disables" a pedestrian noisemaker would probably do so with a switch to re-enable it. Or at a minimum, be smart enough to re-connect it before getting a car inspected once every year or two. Second, at least in CT, EVs are exempt from inspections because they have no emissions to inspect so I never have to get my car inspected. I know MA is much more strict on this though. Third, any 'repair' in your scenario would be a third party repair shop, not governmental revenue generation. Fourth, the owner would obviously have the option of repairing it themselves and returning for a re-inspection. No inspection center I know of in several northeast states would hold car hostage in order to force an owner to pay for a repair for a failed safety item on-the-spot. It's not even that important. It's like the front license plate. It's illegal in every state I've lived in not to have a front plate. Yet, I've never put the front plate on my cars for three decades. Never got a ticket. Very very few people get tickets for no front plate, and even the ones that do are 'fix-it tickets' where you can go back and show that it's been fixed to dismiss the ticket. And the way that government and LEO agencies lag behind technology, it's going to be a very very long time until there's a LEO that knows the current law, knows which cars should and shouldn't make a sound, and under what specific conditions, and be bored enough to write a ticket for that. It's just not realistic. LEOs have much better things to do. If LEOs were interested in writing tickets and generating revenue, around here there are a dozen stop signs that EVERYONE almost ignores (I don't, of course). The cops could sit there and write tickets ALL DAY LONG, generating tons of revenue for the town, the state, and the insurance companies (moving violations and all) and make those drivers safer drivers in the long run. But they rarely do. You think these LEOs are going to concern themselves with a noisemaker not making a noise in a tiny subset of cars?
