I realize Forza wants to appeal to all ages and thus puts in assists for everything except throttle including steering, but it’s usually the people with invalid cars (Dirt tires in road races) or younger people with lots of assists on in live lobbies that crash into everyone.
I wish you would disallow Drag/Rally/Dirt tires in road or street races, but I think a majority of people who do this also have traction controls turned on. ABS is probably the only assist most advanced users/adults use because of being on controllers or older/lower rank cars whose brakes can’t be tuned. Separate live lobbies for anyone below Unbeatable/Pro would probably also work similarly.
As a rank 13 tuner, I can make glitch cars to dominate every st/rd race, but I don’t like driving them or using them usually opting for one of my RWD tunes since a winner as a cheater is still a loser.
