It's different. The leaf blower thing is something everyone has a right to do, and if it actually bothered enough people the municipality would put some restrictions on it regardless, and they didn't have to intentionally seek it out in legal scripture, and anyone can verify that they are using the leaf blower. With the cars, they went out of their way to get the right to do so, implying they want to do it, otherwise it would be a waste of money. Nobody can really verify whether they are or are not doing so, as that's confidential company information and it's not illegal (since they have to right to do so) so nobody can subpoena them to find out. So maybe they are doing it and just lying about not doing it.
