Hibernation for cars with diesel engine

Once upon a time there was a man, let’s call him Mister B., who got excited over everything. Even when politicians presented some extraordinary and well thought out proposals to keep our surroundings clean he was not able to contain himself and reacted very angrily and narcistic. He had a very old and battered knockmobile without any diesel particulate filter, without any equipment to prevent environmental pollution, sort of a real smut-catapult. He couldn’t accept the fact that such a jalopy should be parked at home when the threshold value for particulate matter emmission exceeded a declared limit. He blusterd, cursed and bitched about the persons in charge because of their incompetence and their being worldly innocent. He found hundreds, actually thousands, of arguments to confirm his point of view but a lot of them were far-fetched and completely inconsistent with the result of the lastest research concerning ecology.
Some day Mister B. walked through his hometown and saw a very handsome and beautiful girl standing on a podium in the middle of the park, talking about pollution control and how a lot of people refused to assume personal responsibility for our shared environment. Suddenly he was overtaken by the awareness that he was wrong and was ashamed of having such a position regarding ecology. He decided to become a better and ecology-minded man. Already the next day he went to the nearest Mazda-dealer and bought a Mazda6 with diesel particulate filter. Since that time his ecological conscience has been pacified and he is now able to sleep as well as I do.
