1. The same thing other automakers like GM have been for
decades (OnStar) - Honda is just late to the party.
2. The answer is found in the
2016 Honda Accord Navigation Manual.
If you knew what else Honda and others know about you and your vehicle, you'd probably forget all about this particular concern.
If
location history makes you paranoid, I suggest that you
don't read the following:
Service Diagnostic Recorders on the first page of the Owner's Manual.
"This vehicle is equipped with service-related devices that record
information about powertrain performance."
American Honda's Vehicle Data Privacy Practices
Here are some things your vehicle may record and transmit to Honda and others:
"• oil life, odometer mileage, fuel level, miles remaining to empty, dashboard warning lamps, tire
pressure, diagnostic trouble codes (e.g., electronic system generated trouble or failure codes),
vehicle maintenance status and other vehicle status and diagnostic information;
• trip log information, including trip start time and end time, trip start and end location, trip
distance, and fuel consumed; and
• airbag system status, including airbag deployments and the relative change in velocity (delta-v)
associated with the airbag deployment
• your search content;
• account access information, including information about anyone making a call from the vehicle
or under your account; and
• call history information, including the date, time and duration of call, and any response
specialist’s notes written during a call;
• smart device calendar data, such a date/time/location of scheduled events (for use in navigation
system or system improvements);
• navigation system settings and usage;
• audio system settings and usage; and
• connectivity systems (e.g., embedded TCU, wifi hot-spot) settings and usage.
• vehicle speed; vehicle acceleration and deceleration
(and associated pedal positions);, engine speed;, direction of travel; time of travel; steering
angle; yaw rate; vehicle control systems settings, position and usage; and Honda Sensing/Acura
