As some who likes racing STOCK vehicles with no upgrades I’m very frustrated with the current system in Free Play. In past Forza games it loaded drivatars with a PI index both below and above the PI of the players chosen car. For example if you didn’t restrict the class and chose a car with a PI of 507 it would load drivatars cars between about 460 and 550 (roughly). In this game (Forza 7) it loads all the AI cars with PI much higher than the player cars. Whether I choose “any” or a specific car class it only loads drivitar cars with a higher PI. This is annoying when racing with cars with no upgrades as it forces you to lower the difficulty as the drivatars all have faster cars.
Also it would be nice if there was a toggle in free play in race setup under the advanced car restrictions to force either “production” (commercially available street cars) or “race cars”. When you drive S class for example your grid is full of touring cars and Aussie V8 race cars even if you are driving a production street vehicle. There is no way to race just road cars without changing PI restrictions or specific cars.
