The invention discloses gesture-based vehicle-user interaction. A system, for use in implementing a vehicle function based on user gesture, including a hardware-based processing unit and a hardware-based storage device. The storage device includes a user-gesture determination module that, when executed by the hardware-based processing unit, determines a user gesture, made by a user proximate a vehicle, wherein the user gesture is not an under-vehicle user kick. The storage device also includes a vehicle-function identification module that, when executed by the hardware-based processing unit, determines a vehicle function pre-associated with the user gesture determined. The storage device further includes a vehicle-function activation module that, when executed by the hardware-based processing unit, initiates performance of the vehicle function identified. In various embodiments the technology includes the storage device, and processes including any of the operations described.
