And that's exactly why. Yeah, its new, you'll draw some kind of crowd in. It may not be the kind of demographic you want, but at the end of the day, your "competitors" will get the bigger populous because of the model cars appeal. Its a new style, I get it, but its probably not the kind of style EVERYONE ELSE wants.
I don't know there is plenty of people here who liked it, but hey I can't appeal everyone, so why bother? Even if I'd go for the normal sized cars there would still have people who won't like the game, maybe for it's simple graphics style, or the type of handling, the way the racing works, the possible lack of weapons in it, or for not being realistic, you basicly can't make a game where everybody likes without an exception.
I understand your dislike over the car style we're going for but really, I can't please everyone in every single way, we just want it to be more unique, and I'm fairly sure that uniqueness will bring attention from people.
