速度计，转速表，行程表，燃油表和其他指标都列于最佳位置以保持视野清晰。

The speedometer, tachometer, trip meter, fuel gauge and other indicators are set in optimum position to keep the field of vision clear.

只有疯子才会驾着一部速度计失灵倒后镜裂缝，前挡风玻璃雾蒙蒙的卡车，开足马力全速前进。

Only a madman would drive a juggernaut at full speed with a faulty speedometer, a cracked rear-view mirror and a misty windscreen.

在跑道上，速度可以根据停表等控制(每50m响一下)或者由一辆带速度计的自行车跟着。

On the track, running speed can be controlled with the help of sound markers and visual markers (' beep 'every 50m) or a bike equipped with a speedometer.
