陆地交通的形式,与其说取决于技术,不如说取决于政治、经济和环境方面的考虑。我们现在就可以建造更坚固、更安静、更防滑的道路,但却不建,因为费用太高。我们可以在高速公路两旁安装隔音板并且设计出尾气少、轮胎噪音低的卡车,从而使交通噪音减半,但我们不愿意掏这笔钱。

问题     陆地交通的形式,与其说取决于技术,不如说取决于政治、经济和环境方面的考虑。我们现在就可以建造更坚固、更安静、更防滑的道路,但却不建,因为费用太高。我们可以在高速公路两旁安装隔音板并且设计出尾气少、轮胎噪音低的卡车,从而使交通噪音减半,但我们不愿意掏这笔钱。环保游说者们已对汽车厂商产生了巨大影响,对尾气排放的控制已经严格了许多,但是在控制空气污染方面仍然任重而道远。
