During the qualifying session of the Barcelona GP, an AE86 with a black hood caught up to me on La Caixa. On the start/finish straight, I though I could lose him as I was driving an Audi S1 but he still managed to keep up. He actually tried to pass me on the inside through Renault but I defended position. Suddenly, he disappeared from my mirrors. Upon entry to Repsol he passed me on the inside upon entry. The car was clearly supercharged and had a driver named Akiyama. I swear, that was all Assetto Corsa single player. How?
