$ Yes Daniel, an EXCELLENT ANALOGY of the "PEGGED" VELOCiTY c.!!
For the Pioneer anomaly, you TiLT the floor ..just a little.!!
[Just enough to cause a SMALL increase in the mouse-velocity].
This will help you SiMULATE the AMBiENT GRADiENT of DENSiTY.!!
[There's an AMBiENT DENSiTY GRADiENT between EARth & Pioneer].

$ You can ELiMiNATE your GOLF-cart scenario, altogether, Daniel.
NOW you drop the mouse ("PEGGED" at 3 mph), at the START LiNE.
[Of course, the mouse will "actually" accelerate, DOWN-grade].
[Of course, the mouse ACCELERATEs, _AWAY FROM_ the OBSERVERs].

$ But, the OBSERVERs have DECLARED the 3 mph to be a CONSTANT.!!
[ Having DECLARED the "CONSTANCY-of-the-VELOCiTY-of-MiCE".!! ]

So, ALL the GR OBSERVERs must agree (..especially Ph.Tivitists):

1. The VELOCiTY of the MOUSE has NOT been ALTERED in the TEST.!!
The mouse's velocity, in fact, REMAiNED _iNCREDiBLY_ CONSTANT.!!
[And, has _REMAiNED_ iNCREDiBLY CONSTANT, since the BiG BANG].!!

2. SCiENTiST measure _ABSOLUTELY_ NO TiLT in gym floor at all.!!
[i.e. SCiENTiSTs CONFiRM there is NO SLOPE DiSTANCE to MEASURE].

Note, HORiZONTAL DiSTANCE times 3 mph = SLOPE DiSTANCE times X.

CONCLUSiON: This _VERY MUCH_ ..._QUiTE like_ the PiONEER ANOMALY.!!

Yeah.!! Yeah, VERiLY, VERiLY, i re-reiterate NOW so ye will know THEN.

There is this sticky problem in SR of the SOL being constant wrt
the observer, and independent of the speed of the emitter. After
some reflection I came up with the following:

I recently bought for my grandson a mechanical mouse that runs
by a motor that is battery powered. It is remotely controllable,
but let that be irrelevant hereafter.

As a gedankin do the following: Take the mouse to a large gym
together with a golf cart. Set up the mouse to go in a straight
line. On the east end of the gym are scientists that will be
measuring the speed of the mouse as it goes over a 10 ft measured
course.

On the far west end of the gym, get into the golf cart, turn on
the motor of the mouse and while traveling toward the east end,
hang over the side and drop the mouse 1/4 inch to the floor.
Repeat the same with the golf cart going away from scientists
at the east end. And finally drop the mouse to the floor, with
the cart stationary.

In each case the scientists measured the speed of the mouse as
3 mph.
IOW, the measured speed of the mouse was independent of the
speed of its golf cart source. In each case the mouse attained
its regular speed after some "screeching of its tires". The
speed measured was always its own self generated speed.

Question: From the standpoint of theoretical physics, does the
preceding analogy have any possible connection to the constancy
of the SOL irrespective of the speed of its source.
A mechanical way to obtain source independence re SOL.
