318 Customer information
This data could provide an
understanding of the circumstances
in which crashes and injuries occur.
Data could be recorded by the
vehicle only if a non-trivial crash
situation occurs; no data are
recorded under normal driving
conditions and no personal data are
recorded. However, other parties,
such as law enforcement, could
combine recorded data with the type
of personally identifying data
routinely acquired during a crash
investigation.
To read recorded data, special
equipment is required, and access to
the vehicle or the module is needed.
In addition to the vehicle
manufacturer, other parties, such as
law enforcement, that have the
special equipment, can read the
information if they have access to the
vehicle or the module.
GM will not access this data or share
it with others except: with the
consent of the vehicle owner or, if the
vehicle is leased, with the consent of
the lessee; in response to an official
request by police or similar
government office; as part of GM's
defense of litigation through the
discovery process; or, as required by
law. Data that GM collects or
receives may also be used for GM
research needs or may be made
available to others for research
purposes, where a need is shown
and the data is not tied to a specific
vehicle or vehicle owner.
