Given how top heavy helicopters are, they tend to roll over in a ditch which puts the brakes on all of that spinning rather quickly. (Granted, there are helicopters with floats that keep it more erect so that one can shut down the engines/head before exit ... )
Ditching is one reason people do the helo dunker training before deploying them at sea. With training, the ability to get out once it's all wet is less likely to be fatal, and with systems such as HEEDS added swimming away even likelier.
