Perhaps TimeHorse is not understanding the
tire pressure layout in LEAF Spy / Pro:
As best as the car / app knows, assuming
that the pressure sensors have been properly
registered and "located" on the car...
the upper left pressure is the front left tire,
upper right is front right,
lower left is back left tire,
and the lower right is the back right tire.
Always, in landscape or portrait mode,
upper is front, lower is back
left is left, and right is right.
If there was a car or arrow, it would always be
pointed/headed "up", so it would never give any
additional information, thus basically useless,
unless one needs an arrow on the dashboard
to remind them which direction the car is facing.
Hint: Usually, when driving, one is facing the
front of the car, and the left arm is on the left
side of the body, and the right arm, if any, is
(or was) attached to the right side of the body.
Ok, please excuse the over-simplification.
The real problem is that neither the car nor the
Spy app have any definite knowledge of where
the tire pressure sensors are located.
So, there is the tire-location initialization
procedure, included in the LEAF Spy Pro app.
