The unpredictable AI cornering can also result in a wide variety of AI lap times--and unrealistic AI capabilities.
I've had races where I could not reach the lead F1 in a detuned F1--no matter what lap times I posted. At the end of the race, I was around 10 seconds down. One retry later, with lap times only slightly better, and I'm leading at the start of the 4th lap.
With the same F1 and against the same AI, I reached 1st in the final lap only to be unceremoniously rammed at the hairpin. As I get shunted forwards, the AI F1 moves into 1st with me circling around to end up right behind him. What follows is a burst of acceleration last seen on a vehicle with more than one rocket. Although we both entered the back straight within 20 metres of each other, by the end of it, the AI F1 is way in the distance, hundreds of metres ahead. The replay just confirms the utter ridiculousness of the affair.
Still ... all in all, I'd prefer some quirky AI behaviour to the stock standard mid-corner stop and sudden apparent disappearance of the AI's accelerator.
