If everybody is making cars that handle much better than they do in the real world, wouldn't this result in an arms race of upping the "cheese" of the mechanics to heighten the intensity? And this only works until people recognize the grift -- once they know the actual car experience and the demo experience aren't related, suddenly it won't be a useful ad anymore.
That's not a likely scenario. They aren't trying to create a Camry that handles like a Porsche. They're trying to sell Camrys. The effects will be subtle and plausible. To the extent that it's discovered, there will be excuses. And even after it's discovered, it will continue, just like everyone today knows TV car ads aren't real, but they're still effective, because they tap into the right parts of our brains.
