The FIA has rejected calls to reintroduce gravel traps at circuits.
Over the last decade, a number of gravel traps at Formula One circuits have been replaced by concrete and grass run-off areas.
At the recent Mexican Grand Prix, there was controversy over both Lewis Hamilton and Max Verstappen cutting the first turn, with only the latter being punished.
Former F1 driver Juan Pablo Montoya thinks there is a solution.
"Put in gravel traps and all the debates stop," the Colombian told Germany's Auto Motor und Sport.
Daniel Ricciardo agrees
"I'm a fan of gravel, because it punishes you. If you don't get stuck, you have rocks on the tyres and in the sidepods, so you're not getting an advantage."
But the German publication says that tyre supplier Pirelli isn't keen on the idea
"Pirelli is already complaining that there are too many stones around that damage the tyres," an FIA source is quoted as saying. "With gravel this would be even worse."
