Thats the beauty of it. You can not. Because we do no longer have a free market. All car companies, belong by shareds to a few titanic entities, who will push this in lock step to all there companies. Welcome to the gilded age.
Which “few titanic entities” are you referring to? Tesla? BMW? Toyota? Volkswagen Group? Gheely? BYD? Hyundai? Honda? … the list goes on. Basically there isn’t a more competitive anti-monopoly industry than the car industry.
Somebody who wants to buy a BMW will likely not be cross-shopping with a Hyundai, even if there's are models at the same price point.
The luxury car segment is also huge…
The Chinese car manufacturers are going to eat them alive soon anyway.
