Bending a crank is usually the result of something nasty, like hydro-locking the motor (which also usually eats connecting rods!).
I don't think I've ever seen anyone bend a crank from normal driving. I suppose you could also TWIST the crank if you had big tires and dumped the clutch while trying to pull something (like on pavement) - but again, that's totally weird!
Like Mark asked - is the crank visibly bent? Can you give us some pictures?

I would say you would see your driveshaft flying into the woods first. I have seen engine builders check cranks for straightness and call them bent when just a few thou. out. I was also told that when not installed in a block you can knock them out a few thou. pretty easy. You would never see that though just looking at it.
If you lay them horizontal on the shop floor they will start to bend in a short time. I like to leave them in the block or stand them on end without the counterweights touching the wall.
We had a machine shop check it and they confirmed it, it was a mud racer and had a 3600rpm stall converter, punched .30 over, stage 3 cam, high rise eldlebrock intake, double pumper holly carb 750cfm, bout 400 dollars in work and parts on each head, msd ignition, and to top it off a B&M slap shifter , also 35" tires all the way around.
