Cars are by now a hard to reverse environmental and urban planning disaster across the world. We are stuck with them. As a mode of transport it has grown uncontrollably at the expense of all others (except the airplane) and practically everything has been shaped to accomodate it.
Reversing that development, limiting car traffic to where its really needed is like trying to perform a complete heart and arteries transplant on a living person. Even if there was a will (which there is not) it is not clear if there is a way.
In the best scenario it will be an excruciatingly long transformation (~50 yr) as car oriented cities (or city sections) get slowly deprecated and the car-free or car-lite segments become more desirable, more livable.
The problem is that these are crippled by regulations that only apply to the new transportation modes.
In Los Angeles we put GPS speed limiters and parking enforcement on scooters while letting cars park practically anywhere. You can drive 80mph through a school zone and nobody will do anything unless a cop happens to be there when you do it.
It feels like an antitrust lawsuit waiting to happen.
