几千年后，在英国和美国的一些地方，少数人开始试验用蒸汽做动力，以钢铁做道路。蒸汽火车便这样出现了，它的使用大大缩短了人们远程旅行的时间。不过由于铁轨铺设的限制，人们去大多数地方还只有依靠马车。为了解决这个问题，寻找一种能够完全替代马车的物品，发明家们又开始忙碌了起来。后来经过不懈努力，卡尔•本茨研发出了一种能够代替马车的，就是由钢铁制成的三轮汽车。本茨发明的三轮汽车装载量只相当于两轮马车，并没有舒适的车箱可供乘客遮风挡雨，不能获得大家认可。可金子早晚都会发光的，不久有人对三轮汽车进行了改造，将它变为了四个轮子，并且具有像马车一样的带窗箱子，还让它有了一个好听的名字“无马马车”。 Thousands of years later, in some parts of the United Kingdom and the United States, few people began to experiment with steam-powered, with a steel-made road. This steam train will be there, its use greatly reduces the distance people travel time. However, because of restrictions on the laying of tracks, most places only people to rely on the carriage. To solve this problem, to find a way to completely replace the carriage of goods, inventors began to busy again. Later, through unremitting efforts, Carl • Benz developed a way to replace the carriage, is made of three cars of steel. Benz invented the three-wheeled vehicles loading only the equivalent of two carriages, the carriages are not comfortable shelter for passengers, can not get you recognized. Sooner or later gold will be shining, and soon was on the three vehicles has been transformed, it becomes four wheels, and has the same belt as the carriage window boxes, it also has a nice name, "No Mama car."
