就現今社會來說，機車提供高機動性及價格低廉，因此多數人以此為日常交通工具，亦間接產生相關需求。以基本行車安全來說，除了遵守交通規則外，更要注意行駛速度及路況。就呈現之速度資訊而言，機車基本配有類比機械式之車速器，主要是利用傳動軸之轉動及齒輪機械結構來達成速度之偵測。In today's society, locomotives provide high mobility and low prices, so most people use this as a daily means of transportation and indirectly generate related demand.
