It seems obvious that with out the key present the car should not be able to be driven away at all let alone for ever.

It has to be like this as it could cause a major accident if, for instance, the battery in the key was getting low and then had no charge left when you're driving down a motorway and everything switched off without warning.  If the car detects a key to start it, it'll stay running until it's switched off.
