Can you reword this, please?

Hello everybody!
A friend of mine is translating an article on Formula-1 from English, and she got stuck here:

"I suppose it was because I thought nothing of putting a wheel up a bank if necessary"

It's the answer a racer gave when asked how he managed to perform so well on the most difficult circuit in the world. Everybody was surprised and fascinated with the answer, it's said.
The setting is Nurburgring and 50s, if that matters.
Can anybody please explain what it's supposed to mean?

Thanx a ton!
