Ah gotcha Bill you mean he put an after market clock, a nice carriage clock, in the car and that's doing the job!
I can see that working over my wrist watch, LOL I have a mental picture now....
I like the cookoo clock idea, the weights would get in the way when cornering.......
I have a theory regarding the clock but an anatomical black hole sensor and as the planet slips nearer to the event horizon the real time is slowed. Other lesser car manufactures just fit clocks.
