It should be pretty easy to filter out everything that is not visible to humans.

Great idea, but they are taking it too far. People should be allowed to have a car, but it should be parked at the edge of the neighborhood and only be allowed to come in for loading and unloading of heavy things.

That way you have all the benefits and almost no inconvenience at all. We have that in many places in Denmark and it works great.
