To those who have to squeeze onto the number 25 bus in London, or the A train in New York, 对于那些不得不挤上伦敦25路公共汽车或纽约A号火车的人来说，

the change might not be noticeable. 公共交通的变化可能并不明显。

But public transport is becoming less busy in those cities, and in others besides. 但是在伦敦、纽约这样的城市，公共交通越来越没那么拥挤了。

Passenger numbers are flat or falling in almost every American metropolis, and in some Canadian and European ones, too. That is despite healthy growth in urban populations and employment. 在美国、加拿大以及欧洲，尽管城市人口和就业在不断增长，但是几乎每座大城市的乘客数量都不再增长或已在下降。

Nose-to-armpit travellers may be even more surprised to hear that the emptying of public transport is a problem. 公共交通系统因为乘客太少而成为问题，天天被挤扁了的旅客们知道这一点可能会倍感惊讶。

More than one laboratory is churning out new transport technologies and applications. 很多实验室正在全力研发新的运输技术和应用程序。

Silicon Valley invented Uber and, more recently, apps that let people rent electric scooters and then abandon them on the pavement. 创造优步的硅谷最近发明的应用让人们可以租用电动车，用完后放在人行道上即可。

China created dockless bicycles and battery-powered "e-bikes", both of which are spreading. 中国创造了共享单车和电池驱动的“电动自行车”，这两种自行车都在迅速普及。

Some inventions will fail, or will be regulated out of existence 某些发明要么失败，要么被禁止
