Tip: Rain problem !!!
A note to EA and Codemasters. The problem with the rain is not in free practice or qualifying. It's in the actual race, as I have discovered. I took the trouble to examine the problem closely. I modified the tires so that I had extreme grip and drove the full distance in free practice, qualifying, and the race in Japan.
Conclusion: I was 6 seconds faster in free practice and qualifying. In the race, I was 2 to 3 seconds slower. All this at AI level 100 percent. The problem lies solely in the programming for races. Either the AI has more engine power or continuous ERS because the ERS recharges much too quickly with the AI. Now you have a clue as to where to look.
But it's not really my job to test this, it's yours, dear EA employees. I only did it because it absolutely annoys and angers me that it hasn't been fixed yet and because, as a retiree, I didn't have anything better to do.
