Even with equal performances the IA of drivers perform very different from one another, for example, in online sessions I notice Perez and Russell normally are really fast. In adition, even if they were bunched, I wouldn't really mind, because while trainning my pace I normally don't care at all for the IA performance, I put them on a level where they don't bother me and I just focus on my average lap time. This change would be more so that we can train in other cars besides the Merc, as well as possibily focusing on the onboard your using for your league race.
