我作為美國空軍特遣部隊(duì)的一員駐扎在英國皇家空軍某基地,那里有一條狹窄的馬路蜿蜒穿過擁擠的居民區(qū)。因?yàn)槎啻纬霈F(xiàn)汽車撞傷行人一類不甚嚴(yán)重的車禍,美國空軍司令決定將車速限制在每小時(shí)三英里。
Shortly after the new limit was posted, an MP sergeant issued a speeding citation to a jeep driver for going five m. p. h. I was curious to know how the MP had determined the jeep's speed so exactly. "I was jogging to get to the PX before it closed,” he explained, "and as I passed the jeep, I noticed that the speedometer read five m. p. h.”
新的車速限制公布后不久,一名憲兵中士因一名吉普車司機(jī)開車時(shí)速達(dá)每小時(shí)五英里而給他開了一張超速傳票。我很想知道憲兵是怎樣如此精確地知道那輛吉普車的速度的。“我溜達(dá)著要在郵局關(guān)門之前到達(dá)那里,”他解釋說,“當(dāng)我超過吉普車時(shí),我注意到計(jì)速器指向了每小時(shí)五英里。”
