In twenty years, will be fewer cars in use than there are today?
I'm not sure that would happen in our generation,
cause the technical improvements and forean investments worldwide
seems not to exeed the incomming changes from developing countries.
Demograpy heralds us the remarkable population increase around the world, especially in developing countries.
In Negeria, thier birth rate have agressively increased to exeed 5.0, and Indian population reached 1.4billion.
It demonstrates us the vehcle demands will rise there after few decades.
Now a days we're developing some other means of transport, such as dron caps flying in the air and hyperloops "floating" underground.
But highly engeneered machines demand great budget and infra at the same time.
So 20 years maybe enough for us to see them at wealthy cities,
But it's not enough for them to be commecialized and widespread around the whole world.
Population increase had come very near, and people of new generation will surely perchace a car.
Cause the others will still not be available or afford for them.
