Cars were very few and only rich people could buy them.
However,in England cars were thought to be dangerous at that time,so for a few years someone had to walk in front of every car waving a red flag!This was to make sure that the car did not go too fast and hurt anyone
怎么感觉这段读起来矛盾,前面说危险,后面怎么说不快没有任何人伤亡这里的so for怎么解释!

但是,在英国那时车很危险,所以很多年人们当在车前走的时候要摇红旗(警示车辆),这样保证车不会太快而撞到人.
