1. A motor vehicle, comprising:
a plurality of control devices which are configured to provide a respective vehicle function in the motor vehicle, wherein
the vehicle functions of the control devices are different, and
the control devices are connected by a common bus line, which is led in succession through a respective communication circuit of the control devices so as to connect the control devices one after another to form a daisy-chain circuit,
wherein, in each of the control devices:
a) each of the vehicle functions is implemented, and
b) a processor circuit is configured to:
ascertain a position specification, which specifies a position of the respective control device within the daisy-chain circuit, and
select a vehicle function assigned to the position in dependence on the ascertained position specification from the implemented vehicle functions and offer the selected vehicle function in the motor vehicle for an activation.
