Will this ever be a game of skill or just exploits?

Is it Forza’s intention that people use glitch cars to exploit in more than half of the live races, or are you unable to balance cars and the physics engine so that a GTR with offroad tires doesn’t win in Road and Street races in 700, so that a Bone Shaker with Rally tires doesn’t win in Road and Street Races in 800, and so that an FXX with downgraded Drag tires doesn’t win in Road and Street Races in 900? There are others, like a Hennessey Venom RWD with rally tires for 900 Street, but those are the common ones.
All I can fathom is either you intend to promote what most consider cheating or you’re unable to put tire restrictions in races and cannot balance cars and tires properly.

I am genuinely curious. After all, I have over 450 tunes that I don’t bother sharing because everyone just uses the exploit cars live. Is that all Forza wants, glitch car tunes that drive like garbage but accelerate in a straight line faster, especially with assists on?
