AI final laps we know are fast (as they have always been in the past games), EA staff also explained why (use of ERS etc.).
Just completed today a 100% race in Bahrain, 5 laps to go I was catching Russell lapping 1:32.1 gaining a couple of tenths per lap (with Verstappen the fastest in 1:32.0).
My last but one was the best in 1:31.9 without much ERS to use.
In the last two laps AI were flying, Russell 1:31.7 with H at their 32nd lap, Verstappen 1:31.1 with H at their 41st lap (!), while I was with M at 25th lap.
We know the player needs to be ahead at 3 laps to go, possibly a couple of seconds at least and defend the position. Yeah, I agree it probably doesn't make much sense.
