My present cars all have speedometers which, with varying
degrees of accuracy, indicate my speed relative to the
surface
of the Earth.
This is all very well and good, especially since speed limits
are also often expressed relative to the surface of the
earth.
Howevertheless, I would like
a less restrictive speedometer.
Using an additional menu on my SatNav, I would like to be
able to specify any known object in the universe. It might
be
the Great Red Spot of Jupiter; or Antares; or the
Andromeda
galaxy; or the sun; or the Duke of Edinburgh. The
speedometer would then indicate
my
speed relative to the specified reference point.

If you set it to show your speed relative to Ed Milliband, it would read "Going nowhere, fast" ... |

What about just your speed relative to the car in front?
Some new cars with the "follow the queue" function do this (I guess) but displaying it would cool (especially if it was done as a vector; relative speed and relative direction). |

Yes, but that wouldn't be very exciting. My speed
relative to Ursa Major, however... |
|
| |
… would be bearly measurable. |

This could be done as a phone app. You could then measure your relative speed against other app users. This could solve the problem of knowing the direction and velocity of His Royal Highness. |

I like this as a social network feature so long as it doesn't reveal location, just relative speeds. Is that a privacy issue, though? If you stand still and your relative speed to Kanye West is 500 mph, he's (probably) flying. Vague enough perhaps. |

he is God. |

You could quite easily install a speedometer that is relative
to yourself. Just a gauge stuck at zero. |

Some of my relatives zoom about in endless frenzy.
Others need to be watched carefully for signs of
movement. |

If the vector was integrated, you could determine
location, if the starting point was known. |

Ah, but we're measuring speed, not velocity. |
|
| |
Walk in a circle and watch the relative speed change to discover the velocity. |
