It is the debate in Formula One that has got everybody talking.
And now, fresh from his triumph at the US Grand Prix on Sunday, Lewis Hamilton has had his say on the Max Verstappen-Kimi Raikkonen saga.
20-year-old Dutchman Verstappen initially finished third on the podium, but a five-second penalty deduction saw him finish fourth, behind Finn Raikkonen.
Verstappen was adjudged to have maneuvered past his opponent whilst all four wheels of his car were off the track, leading to the subsequent penalty for the Red Bull man.
32-year-old Hamilton, who can win his fourth Drivers' Championship at the Mexican Grand Prix next Sunday, has called for more clarity.
Speaking to Sky Sports, Hamilton said: "He is off track, this is the problem with today's circuits, I don't know who made the decision, but there is all of these run off areas, if it was grass, he wouldn't have gone there, nobody usually goes there.
"There are these flaws on the circuits, and particularly the newer generation of drivers come in and they are more than happy to come in and try and exploit those things. Clearly he is way off the line and you can't go there.
Watch Hamilton give his analysis of the incident in the video below.
"It is very difficult and when we are in divers briefing we are always discussing whether you can gain an advantage, there is an argument to it. We can go on the power 10 minutes earlier and just go wide.
"There is a really fine line but I think the FIA to a good job, but when they come to building these new tracks, they can't build these big run off areas.
"It is strange, as here (The US Grand Prix) you couldn't used to go wide on exit of nine, and now you can go over the track, and last corner you can just go over the big curb."
