AI STRAIGHT LINE, TYRE WEAR, AI ACCELERATION, AND WET RACES.
AI straight line speed - despite the new update with the straight line being affected by the ride height and all that haven't really worked as the ai still have a massive advantage and makes you drain all your ERS down the straights despite having drs and the ai dont... even when there is 3 cars within drs, the player would still lose out and not be able to gain time or anything.
Tyre wear - especially on controller has still been terrible, that is probably one of the biggest problem that hasnt been fixed yet, im using max tyre pressure and i still cant make it to lap 12 on mediums without having over 70% tyre wear, and for most tracks, while the AI easily can make a 1-stop.
AI Acceleration - Acceleration for this years game hasnt been the strongest one compared to last years game, but its still decently bad, i get good exists but still lose around 2-3 tenths.
Wet races - had one full wet race since the start of the new patch with the it wasnt completely terrible although they still were like 1 second faster with a full wet setup, the automatic gearbox patch didnt help completely either as they they still flew away and gained like a 9 second gap on lap 10-11, and the inters burn way quicker too, especially the rears.
