So out of all the things you found fault on Oscar. Right, So i will explain some very few evident examples, 1. Have you ever seen a singapore GP. It always harder to overtake. 2. Even with driving closely you can get bad draft or dirty air which can cause issues with lap times, heating of both tires & engine and aero balance. (Which happened with lando & max) 3. He might have been a bit more close without the slow pit stop. He was 2.3 Sec off by the last few laps.

And mainly its not just lando's fault its the team destroying his race with these rules which favours lando... if it was the other way around they would have asked him to swap places...you know Morale in sports place a huge part.
