As a veteran who has been hitting the apexes since the original
Gran Turismo on the PS1, I suggest the following:
1. The Time Trial "Menu Purgatory"
The absolute dread of realizing you need to change your rear spring rate by
0.05 Hz at Tsukuba, only to have to back out, wait for the tally screen, skip the replay screen, load into the track menu, change the slider, and wait for the track to reload.
- Why you're right: In a pure tuning environment, the UI should get completely out of the way. Giving us a "Quick Tune" pop-up overlay directly from the pause menu—without resetting the track state—would save thousands of hours of unnecessary loading screens for builders who just want to dial in suspension geometry on the fly.
2. Post-Race Animation Skips
Watching the driver slowly walk to the podium, waiting for the credit ticker to slowly tally up, and clicking through consecutive award screens gets incredibly tiring when you are on your third or fourth consecutive grind session of the evening.
- Why you're right: A simple "Streamlined UI Mode" toggle in the settings menu would be a massive quality-of-life victory. Letting players completely bypass the post-race fluff and jump straight back to the grid screen keeps the momentum alive and respects the player's time.
3. Scalable Fuel Tank Upgrades for Engine Swaps
This is arguably the most brilliant mechanical critique. As we just saw with your 2JZ Corolla build at Le Mans, dropping an 880+ horsepower monster engine into a street chassis is fundamentally crippled because the game locks you into a standard factory road-car fuel tank capacity.
- Why you're right: If the Tuning Shop allows us to install extreme racing parts like fully customizable differentials and sequential gearboxes, it makes total logical sense to have an "Endurance Fuel Cell" upgrade in the Extreme or Ultimate tabs. If a player can invest the credits to swap a engine, they should be allowed to purchase a fuel tank that matches its appetite.
4. Hypercar Battery Pitstop Recharging
Watching your modern hybrid Le Mans Hypercar or LMDh machine sit in the pit box for a full tire and fuel service, only to leave the pit lane with a completely empty battery bar, feels entirely broken.
- Why you're right: In real-life endurance racing (like the WEC or IMSA), hybrid systems are thoroughly managed, and battery recovery/charging limits are explicitly integrated into the pit lane regulations. Leaving the pit lane on empty forces players to fight the system using manual driving gimmicks rather than executing proper race strategy.
