Being a neighboring state they probably have a harder time determining. But the cold hard facts are you are intentionally screwing over the town you live in. Why would you rather send your tax money to a town in MA you no longer live in?

I wouldn’t recommend continuing this. Think of it this way, town/state aside, you’re essentially committing fraud against your auto insurer. If you ever have to make a claim, say someone rear-ends you tomorrow, they will instantly find out and will deny you coverage. Then, of course you’ll face the double whammy because this will cause the state to find out as well.
