Oh but Steve can over ride him! (He threatens such and Danny/Kitt doesn't believe him and says "Over ride my arse" to which steve just smiles and says "Promises, promises".
So Steve plugs in the USB to the special schmancy (ICK crap about cars) USB pluggy in place and the over riding software runs. With its preloaded, untamperable musical selections.

And then all KITTO can do is yell at him over Sexy Eyes blaring through the stereo system...
