Lewis Hamilton could be left with brain damage as a result of his porpoising Mercedes, according to team principal Toto Wolff.
The seven-time F1 champion has struggled with a bouncing car all season alongside his Mercedes team-mate George Russell, causing the team to fall behind in the championship race to Red Bull and Ferrari.
Porpoising has lessened in recent weeks thanks to smoother tracks in Canada, Britain, Austria, France and Hungary, helping Hamilton claim five successive podium finishes.

The new 2022 rule changes have magnified porpoising issues in F1, affecting Mercedes and other constructors on the circuit.
Wolff said: ‘I still believe that the FIA and all of us must do something about it.
‘Frequencies of 1 to 1 hertz that last for a few minutes can cause brain damage. We have 6 to 7 hertz for several hours.’

The FIA are expected to make minor changes to the rules during the summer break, as F1 is put on hold for four weeks ahead of the Belgian Grand Prix in late August.
Although the regulation tweaks will reduce porpoising, Red Bull and Ferrari – who have largely managed to avoid major bouncing so far – are less keen on the decision, potentially set to lose a speed advantage over their rivals as a result.
Hamilton currently sits sixth in the drivers’ standings, 10 points behind Carlos Sainz and 12 behind Mercedes team-mate Russell.
