1. Endurance save points
2. Better track generator (so you actually choose how you want it, not some random track)
3. Event generator (you pick a track, opponents, number of laps/hours and payouts).
4. Better choice in HUD menu - in an endurance, all I want to know is the amount of fuel and condition of tyres. Nothing else, especially the names of drivers which are made up and tell me absolutely nothing.
5. Fast-forwarding B-spec.
6. Mental & physical strength is utter nonsense, there is no difference whatsoever. Get rid of it.
7. More cars at the same time in UCD and possibility to buy them all without leaving UCD menu.
8. Possibility to fast-forward oil changes and car washing. It is nice, but after 35872039th time it gets boring.
9. Why can't I change wheels on my F430 even though it's a premium? Fix it.
10. Remove limits on giving cars.
11. Increasing payouts.
12. Qualifications for events (not all)
13. Maybe another grand tour? Maybe: Top Gear Test Track -> London -> Le Mans -> Eiger -> Monza -> Cote d' Azur -> Madrid
14. Maybe possibility to fully tune car at once (engine stage 3, lightness stage 3, fc tranny, fc LSD, fc suspension, soft slicks, etc.)
15. Possibility to sell ALL cars for decent money.
16. Possibility to remove items from cars and place them on others.
Lol, writing these things down made me realise how flawed this game is.
