In previous Forza Motorsport and Horizon games there was an option to borrow the car from the party/convoy/lobby leader. This was a great feature that my friends and I used a lot.
It was great for setting up cup races, or to get feedback on tunes without having to share it 20x times for every minor change that’s made.
I would like to see this feature return, firstly for Private Multiplayer (host car). Maybe it’s also possible for Featured Multiplayer with the party owner, but this is less of a priority for me.
