When Vesper is kidnapped by Le Chiffre in Casino Royale, Bond chases after them in his car and ends up crashing in order to avoid running over Vesper (who has been left lying in the middle of the road).
Bond is injured (almost certainly concussed) and is subsequently captured.
Le-Chiffre then tries to torture the bank account password out of him.
Now I thought it was a pretty big gambit on Le Chiffre's part to expect Bond to crash his car and just end up incapacitated. If Bond had managed to avoid the crash, he almost certainly would have rescued Vesper and gotten away. On the other hand, if Bond had been fatally injured in the crash, the password would have been lost to Le Chiffre.
What made Le Chiffre so sure his plan would work?
