As for Vettel and Leclerc, both feel gravel rightly punishes a driver for making a mistake, with the four-time F1 champion suggesting a potential mix of gravel initially to catch the error, followed by run-off should a driver lose control.
While Masi recognises their remarks, he replied: "We can't have them everywhere.
"It's not a one-size-fits-all. As I've said multiple times, we need to come up with the appropriate solutions with each of the circuit owners and operators.
"We'll continue working through that. We've already discussed it with the drivers. So I think it's a bit much to ask. It's not the solution everywhere, let's put it that way."
