You have to apply your point about awareness to your reasoning about product placement. You don't start with everything that exists in your head, all of them having a 50/50 chance of existing, and then seeing the car reduces this chance. You have a certain number of car-related stuff, that is probably less than all the car related stuff that exists. Some is marked as real, some as fictional, some as not sure. When you see that Canyonero, it'll be added to your mental space. It may not be in a great position, but it's probably slightly better than not existing at all.
