When you select a car in “My Cars”, there is a link to “Race In Free Play”; a similar link to “Race in Rivals” would be incredibly useful.
I usually end up going into “My Cars” to find out what class the car I want to drive is in before going back to rivals, selecting that class, the track I want and then the car. I almost always choose the car I want FIRST and the menus make this really awkward.
It’s a very small change to implement that would give a MASSIVE quality of life improvement.
