It's not an "all or nothing" thing, nothing is or ever will be. The stat is a glimpse into the mind of the average GT6 player and IMO, it negates the argument that building a garage is something that appeals to a large percentage of players, because it simply doesn't. For most people, the large car roster is not utilized and 96% of the cars are never driven by 70% of the players. That's not to say some players don't drive them, of course they do, but the case for a broad appeal for a huge car list as a reason for keeping the standards just doesn't exist and the numbers seem to support that. It opens the door to an argument that perhaps the objective should using the efforts made to semi-upgrade seldom used standards and incorporate them into the game design, might be better spent modeling a more targetted car list, both with more representation of current models and specific standards upgraded to premium along with catering to long requested fan favourites, and an across the board consistency in quality.
