The funny thing is he is still trying to steer after the wheels have come off.

Toro Rosso said the crash had been caused by a failure of the front-right upright, which caused an immediate failure of the same part on the left.

The crash happened with 10 minutes remaining of the first session while Buemi was on only his sixth lap after sitting out the majority of the 90-minute session because of a brake-system leak.
