There are provided systems and methods for utilizing a vehicle to determine an identity of a user. A user may establish a vehicle as associated with the user, such as a vehicle owned by the user or used by the user. The vehicle may include a vehicle device that may be configured to establish connections with other devices using short range and network communications. In various embodiments, the other devices may be devices at merchant locations. Thus, a merchant at the merchant location may be informed about settings, preferences, and/or parameters for use of the vehicle established by the user. The merchant may receive these parameters even if another user is utilizing the vehicle, thus, establishing rules for use of the vehicle by the other user. In other embodiments, the other devices may be devices in other vehicles, allowing the users to communicate and set waypoints during trips.
