Maybe we can have an "Automatic" button, where the PC chooses like MarcG suggested (for quick races) and a "Manual" button where a (big) window appears, where we can select multiple (not one by one) from all cars (best sorted in categories) by checkbox which cars/drivers appear at the session(s). MarcG:One thing is booting and adding ai, would be better to select number of class cars in the opponent selection screen, posted similar in the wish list forum ages ago amongst other ideas related to class racing.
