Road guarantees us the maximum convenience for those who want to go. It is not the question of where to, or what for, but to go or not to go.
So the chance is that you could go to see a good doctor via the road, while a bad robber could go to your home via the same road. You can export your rice and potato to make money, and you must import a lot of clothes and gadget to pay money. Inevitable.
Just like our information network, we often say that modern transportation system distracts our peace of mind. If that is the case, we should blame our communication itself. And of course we are not angels.
