I think even with a penalty, it probably wouldn't have affected the end result. As @ChickenSandwich noted above, Lando probably should've backed off & tried again. Far less risk that way. What I hate is the continued inconsistency in this kind of steward call. More often than not, overtaking off the track gets the overtaking driver a penalty, even when forced off more forcefully than Yuki on Lando today. Yuki, of course, deserved the penalty for weaving, etc. He did leave room for Lando to keep his right side wheels on the track though, and normally we see the overtaking driver either give back the spot or get a penalty based simply on overtaking off the track, which we're always told is just not ever allowed, even when you're forced off. Except when it is. But whatever. F1 officiating is incredibly inconsistent. Water is wet. And it likely didn't matter. Good season. On to testing.
