Sorting Leaderboards by Car

After many years away from console racing I am a month into Forza 6 on Xbox one S and really enjoying it. One frustration: Why can’t leader boards be sorted by car?

I realize they can be sorted by Division but that can then involve a LOT of scrolling trying to find some times posted with the car I am using. I would have thought most (many) people posting times in Rivals want to compare to the exact same car they are using not something in the same division which could have totally different spec/handling.

Because you can only have one time on the leaderboard. There’s usually a lot of fast cars but you won’t be able to find them because usually that player has a time set in one of the fastest cars.
