Hibernation for cars with diesel engine

Well, interesting topic and I could not agree with Bernhard more!

We will also have a problem with our car, powered by a diesel engine and not having a diesel particular filter, when a ban on driving becomes reality. Thank God, that we live in the center of Graz and therefore we are not dependent on a car all the time. We just actually need it when we go to a supermarket once a week to buy all essentials for daily live (peanuts you anyway buy in the store round the corner), have to transport bulky and heavy things and in summer when we drive to our parcel on a lake near Gralla. This is also the reason for our automotive choice -> we have a Fiat Ducato with large capacity (it also provides enough room to sleep therein :-)).

So, what to do when we aren't allowed to drive with our car: In summer the problem doesn't exit and else in case of need we could do our shopping walking more often in a week, so that we don't have to carry heavily.
However I would like to know how this order should be controlled. I doubt that we have enough police to do this job.

It seems to me that the whole thing is just a new way for making money (producers of particulate filters, garages and the city treasury are already happy or rather will be when the first penalties are distributed), because the 'real producer' of particulate matter, as already mentioned by Bernhard, aren't kept in mind.

In conclusion I think we will be able to live with that, but I don't know what people who are dependent on their car and don't have enough money to refit their cars or buy a new one, or have a car for which no appropriate particulate filter exists (like Karl) will do when the ban on driving for diesel cars without a filter is enacted.
