Egad, you young whipper-snapper, you must be in a testy mood today!
Same here, horrid WX. OAT is 82deg, RH at 20% and the breeze variable
1-3 Kt. Fires in Mexico have poluted the air and my eyes are burning!
(Your terms, "cold, rainy & windy" aren't understood.)

Sorry that I wasn't clearer. Intent wasn't to call for not moving the
seat with someone in it.  I buy six and twelve-way seats to take the
pain out of a long drive.  My tip was just to not ride between the fore
and aft limits several times each day.

After the seat repair, the service manager suggested reprogramming so
that the seat didn't traverse to EXIT each time the engine was shut
down. If the car is garaged, we reach through the window and make the
driver choice, waiting for a few seconds while the seat repositions
before opening the door.  In the wide open spaces, we hit the fob far
enough away so that the seat has time to cease movement before the door
is opened.  (Scary -- I don't have a solution for that. Just live with
the world as being a "sharp and abrasive part of the Universe!")   While
this workaround (for a rather poor seat track design) takes some
deliberate thought and a few seconds, it seems to be paying off in the
long run.  The first track failure occurred in only 18 months.  Nearly
two years of experience with the "revised" procedure and DIC programming
hasn't resulted in any seat "wiggle."

The seat memory isn't needed on the C5 since my driving position is
within an RCH of the full aft seat travel.

Don't know whether there's any truth in the story but I was told that
the seat components were designed by SAAB.  Perhaps they had the lithe
Swede body in mind and didn't allow for the heavier American seat rider.
 One other factor may be that the whole driver's seat assembly in the
Buick is much heavier than the seat in the C5.
