it is the establishment of really practical public transport networks
totally agree ... it is starting to happen little by little. But it's a long-term job, and then most people have to buy into it. For now, the roads are always as busy, the guys will always buy their newspaper or their wand in the car ... Things will be turned around by the wallet. And proof of it is, the price is not yet high enough!
On the other hand, making this public transport free is not, in my opinion, a good thing, we must make people responsible!
