A cemented carbide has a <70 m, preferably 10-40 m, thick binder phase enriched surface zone containing W and Mo but depleted in cubic carbide. One such embodiment of a vehicle comprises a mirror assembly mounted to a vehicle door and configured to rotate about a substantially vertical axis between at least a first position in which the mirror assembly is extended away from the vehicle door for use while driving and a second position in which the mirror assembly is folded forward toward a front end of the vehicle. The microcontroller is configured to record the information received by the display panel from the processor in the storage device when the debug card is connected to the communication bus. The webpages can then be ranked according to the potentials of the nodes to which the webpages correspond.
