I kick over my motorcycle a couple of times before I turn on the ignition,
to start the oil pumping. 

The metal rubbing doesn't hurt when the starter is doing the moving. It's
more of a problem when the engine starts right up and runs before the oil
pressure is up. So I think putting an ignition kill switch on the car to 
prevent it from starting too quickly is a good idea.
