Nonetheless, we’re undecided that’s well worth the time and expense of putting in an aftermarket package in your 10-year-old beater that doesn’t have them. Alternatively, we don’t see any actual hurt in having them, even when they don’t present extra security. Mandated or not, they’re right here to remain for the foreseeable future.
