I would like to be brief. I think a pit stop should be a physical driving effort to initiate pit limiter and a mini-game for time by pressing a series of buttons during tire change/refill or else you may lose a tire, time or accrue a penalty, parking error etc.. I think a yellow and red flag are needed plus damage to engine at least. As much realism as possible and if you dont follow you get penalty until your dq’d. And points toward your license.
I think the driving levels should be license based, the career should have you build your team and obtain a championship and a different sponsor opportunity. Credit Immersion. And I think a online league option to run cars based on preset BOP with their respective changes that are visible to players for trust. And TCS should have levels to them if possible. Insurance and all IMMERSIVE ideas are encouraged for the next Motorsport title but this is my two cents.
