Cars feels like a bit of an odd one out because there's basically no low end. If you have the money to produce even a single car from a Camry to a hummer, you are probably going to not try to pinch pennies on marketing because a single car sale pays the salary of a designer for a year.
That's true. And car commercials that get people to buy fancy new cars are really well figured out and seem to seriously work. Why fix something that isn't broken?
Real estate is interesting because they seem to be really getting into using AI to stage individual houses. So I guess on the same vein maybe someone will try making an add with AI that shows some car driving down your local mainstreet or at some scenic location nearby your ip address that you might have positive associations with. Or maybe even your own home-street and parking in your driveway and you (or facebook you from 10 years ago when you had that hipster-moustashe because you haven't updated your photo) opens the door with a big smile on your face).
Seems crazy, but who knows.
