Fernando Alonso and Mark Webber: Interlagos 2003
Before he was a two-time world champion,
Fernando Alonso ignored yellow flags and debris on the track.
Only once, mind you.
Mark Webber's initial crash was bad enough alone, but what followed was among the among the most hair-raising incidents I've ever witnessed in Formula One. Alonso hit a wheel that had come away from Webber's car, instantly destroying his suspension and sending him into the tyre barrier at high speed.
That wheel could have gone anywhere, and Fernando was very lucky to hop out with no lasting injuries.
He was even luckier to end up classified third in the abandoned race, though he did miss the podium celebrations while he was being checked over.
