This is true (I'm from Europe myself). But I think the diesel fuel is a little different in the states compared to the US (it's not as clean or something), there was another thread about this a while backIn Europe the majority of cars are diesel, and many will be driving in cities. This is a euro designed engine, for cars and trucks. That said, if I were taking several short drives of 1-2 mikes or less, with short stops between, I currently idle my car. Just don't idle too long. It's hard on any engine to have many on/off cycles, especially if not warmed up. Also, don't place large loads on a cold engine.
