Today, automotive data are generated, transmitted, retained or shared for different purposes:
– Data to operate a car: These data are generated in a car, but not transmitted outside. These data are processed by the car’s systems to ensure functionality and operation of the car. From steering to braking, crash avoidance, and acceleration, dozens of onboard computers simultaneously share information as consumers travel down the highway. This data is not transmitted outside, or retained in the long-term computer memory of the vehicle. Users can take this information out as they consent to provide info as part of a subscription service.
– Data transmitted outside of the vehicle: Certain functions can require the transmission of data outside the vehicle. For example, automatic crash notification systems transmit data so that emergency responders can be directed to crash scenes with information on the nature of the crash. Diagnostics systems may transmit data outside the car to identify potential maintenance issues.
– Data transmitted into and out of the vehicle: Navigation system and infotainment system use these data to provide users with better experience while using the vehicle. For example, vehicles can transmit and receive data so consumers can remotely monitor where their car is, remotely start their car, obtain vehicle diagnostics reports and access on-board information services.
– Data that is shared: Technical data regarding such matters as warranty or safety is shared with authorized dealers, who also share this information with automakers. Some information may also be shared for marketing purposes, but only with express, affirmative consent by the vehicle owner or registered user. Government also requires several information from the vehicle like vehicle’s safety systems, emssions controls, etc. to ensure the vehicle is safe to use.
