It's not exactly healthy for the starter motor but can be useful in emergencies for getting the car over to the shoulder or out from the middle of a junction.
I'm not sure how it'll work with automatic gearboxes (a small minority of cars here in the UK) but no reason why it shouldn't work on any car with a manual gearbox and key ignition.
In an older car, even if there's an engine failure, it should be possible to get the car into neutral and either let it roll or propel it with the starter motor to the side of the road. Similarly the brakes will still work, although they'll be very heavy once the assisted-braking is depleted.
