My pet peves...
The rain physics is silly. Its more like ice physics than rain. Nothing worst than being unable to go straight while the AI cars with same slicks get traction and go by you. At times, they also on slicks, run with you on rain tires. Ridiculous.
Traction control is broken. It does work in the rain which is a glaring problem. You can turn it all the way up and its like its totally off even in mild ran at times.
Penalty system is cheap especially in the rain. You get silly penalties even when you on the road and did not go off track. Also, in real life you get track limit warnings before you get penalties. Lets use some realistic common sense on your real driving/racing simulator PD.
Broken pit stopping for AI cars. I've noticed on Le Mans during rain, they will pit the AI Viper and it comes back out on slicks. Utterly broken. I missed the first iteration of this games programming on this track where the Vetter and Viper went at it hard and you were not sure which one will win the AI battle. Now the Viper is programmed to corner much slower, less air/fuel ratio so its much slower so the racing is between those two is dead. Wish PD would pay attention to details like this as it adds to the racing feel.
Low payouts for our custom races. Ridiculous. Why?
Certain cars that are widened get the same size tires front to back. The widened Porsche 930's, for example should have wider tires in the back like the Vipers do.
Racing suspension that's really not racing suspension, ride height-wise. We get everything out of the suspension except the true racing ride height adjustment, visually. Cars like the Gen II Vipers and F 430's, to name a few, suffer badly from this lack of visual lowering. It just kills the visual impact.
Not enough modern cars that are incredibly relevant. In stead we get Subaru's, Silvias, Coppens etc. Where are the 458 Speciale, Pista, Performante, Viper ACR, C8 Z06, C5 Z06, Aston Martin newer cars, Konigseggs etc for street car. For race cars where are far more relevant historic racing cars like the Porsche 935's, Oreca Viper GTSR's, Lister Storms, 993 Porsche GT2's, Vette C5R/C6R, Ferrari 575 GTC Evo etc.
PD formula racing cars don't have the ability to put stickers on tires.
Continuous missing car thumbnails in your garage over time.
If PD wont give us certain cars like the ACR, 935's as stand alone cars, could they just give you the parts in body modification section? They kind of did that with the CSL '73 but they left the rear bumper on...SMH.....The attention to detail in this game is very lacking. Really could have been such a great polished game if Kaz showed even a little of the attention to detail he had with GT4.
