Cutting a corner and gaining an advantage in a way that requires someone to concede a position doesn't happen every race, but I think it's regular enough (multiple times every season) that maybe it's worth having a more systematic and clear-cut solution?
Would it be worth having a designated "conceding zone" on each track that's made known to teams before each race? Kind of like the "long lap penalty" system in MotoGP, except it doesn't need be an explicitly-painted area on the track; more like "entry to turn 9" or "within X hundred meters of the apex of turn 4" or whatever. And the zone could be pre-determined in a way that (barring exceptional circumstances,) it wouldn't be possible for the conceding driver to regain the position immediately after. Additionally, enforce that it be done within one or two laps at most.
Pros: Deterministic approach, should result in "justice" being served for most cases, takes control away from drivers/teams trying to get clever and consequential bickering, prevents a worse version of the Ver/Ham incident from happening.
Cons: Eliminates an element of strategy, might be construed as a knee-jerk reaction, prevents the Ver/Ham incident from happening so less viewership / $$$ for Liberty.
Thoughts?
