2015 Belgium Grand Prix

It is quite obvious actually, Pirelli need to bring the cliff back. And the cliff window need to be wide enough for the drivers to get back to the pits without tyre structure failure. The cliff window should reduce the effective grip of the tyres to a level that would force the driver to lower their speed to a level safe enough for the tyres to withstand the drive back to the pits. This characteristics need to be consistent across the tyres in the set fitted to the car. for instance, one rear tyre should not be cliffing while the other three are in the racing zone, this would be dangerous.

I think if marginal tyres is the way, then do it properly and safely. That said, l am a fan of Pirelli. I think they have done a difficult job admirably. It can't be easy making marginal tyres consistently as they have done. But it is clear that the marginal tyre days are approaching their end. Safety should not be operated as a Russian roullette.
