Regarding M.F. of Bath's comments about digital readout speedometers, another major advantage is the ability to switch the readout between mph and kmh. I have a 2006 Honda Civic Si with that feature (also it's a separate readout above the dash and with large numbers in the driver's line of sight) - great for when I drive from the USA (mph) to Canada (kmh). In my wife's Honda CRV I have to pay very close attention to a smaller size, secondary kmh scale inside the mph scale.
