I don't think it would be inappropriate to rule that the rigger and/or driver would not have access to these systems, unless the spirit allowed it. They'd become as much a part of the spirit's new body as the tires or windows would, after all.
I think the rigger would get dumped (and suffer dumpshock) if rigging a vehicle that got possessed, now that I think about it. The electronics cease to be normal electronics upon possession, IMO.
Street Magic Sidebar p.102
"While the spirit may use all of its powers on the physical
plane through such a vessel, it may only
animate it to perform actions the vessel could
otherwise mechanically perform. For instance,
a possessed gun would be able to fire or eject
a clip, but would be unable to move by itself or
access its smartgun functions. Likewise, a possessed
bright-red SAAB Fury would be able to
drive itself, but not access GridLink, use a Pilot
program, or target weapons with sensors. As
a rule of thumb, spirits can control mechanical
functions, and not those which require complex
electronic, DNI, or wireless controls. Ultimately,
it’s up to the gamemaster to rule what the spirit
can control and what it can’t.
The combined entity uses its enhanced attributes
(or simply the spirit’s if it lacks attributes)
to calculate Initiative, and uses the spirit’s normal
Initiative Passes."
From the bit about grid link and sensors I think the rigger would still be jumped in.
