TaximeterIn 1907, the first internal combustion-powered cabs in London with taximeters began operating. The taximeter gave the cab its modern name. Its purpose was to indicate to both driver and passenger the distance travelled and so avoid arguments about payment due. The word derives from French (taxe = price) and Greek (metron = measure). The taximeter was invented by Wilhelm Bruhn in 1891. |
