Heartbeat of America

From a Chevrolet radio commercial I heard on the way to work this morning:

"For years we've been breaking the rules; now we're rewriting them."

Which is to say...what? That they used to be for radical change but now they're incrementalists? That's what it sounds like, but is that what they mean? Or did they just like the rhythm of the sentence, without giving any real thought to the message?
