I have a little SatnavIt sits there in my carA Satnav is a driver's friendIt tells you where you are
I have a little SatnavI've had it all my lifeIt does more than the normal oneMy Satnav is my wife
It gives me full instructionsOn exactly how to drive"It's thirty miles an hour" it says"And you're doing thirty five"
It tells me when to stop and startAnd when to use the brakeAnd tells me that it's never everSafe to overtake
It tells me when a light is redAnd when it goes to greenIt seems to know instinctivelyJust when to intervene
It lists the vehicles just in frontIt lists those to the rearAnd taking this into accountIt specifies my gear
I'm sure no other driverHas so helpful a deviceFor when we leave and lock the carIt still gives its advice
It fills me up with counsellingEach journey's pretty fraughtSo why don't I exchange itAnd get a quieter sort?
Ah well, you see, it cleans the houseMakes sure I'm properly fedIt washes all my shirts and thingsAnd - keeps me warm in bed
