#8 Haha, no wonder! I mean, the government can efford it . they are rich, very rich. Look, Luxembourg has a population of approx. 650000 people and they life in an area of around 1000 sq miles, Ok, they might need more than one Bus to serve all districts. On the other hand - I can imagine, most of the citizens will go by one of their own cars. Well, their own luxury cars. Sorry, this is just my personal prejudice, I know i'm wrong. But I like to listen to their very own national language, Luxembourgish. I do not understand the very most words, but it sounds very friendly and you feel "close" rather quickly.

#8 It's not free, it's payed by the tax payer. So s a citizen you pay for transport whether you use it or not. Socialism....

#9 I always thought the lights were blue because of color blindness. Like they had enough colorblind people that blue is more apprant then green (which I think the world should actually adopt).
