There is a database for Switzerland, and some sort of paging service to alert you to new installations. A friend of mine was right into that sort of thing. If anyone is interested I'll ask him for details.

Where have you seen these unmarked cars pulling people over quite often? I've seen it in dodgy areas where they are looking for drugs etc, but not "highway patrol".

Another interesting tidbit following on from my 3 warning signs story earlier. The government in NSW provides a list of speed camera locations for drivers:

Now if only canton Zurich would be so kind as to provide the same service... I don't think that's going to happen somehow..

Regarding the mobile cameras in CH - I've also had some friends that said that they've been done by mobile units, though it's never happened to me. I just keep getting loads and loads of the 1km/h over the limit fines. I do try to be good, but when you get fined for being 1km/h over it gets a bit ridiculous (though they are really generous and say that the clocked me at 54, but take off 3 for tolerance). There's quite a stir about this 3km/h tolerance business among the public. Personally I'd prefer that they spent more money taking the drink drivers off the road than fining me for 1km/h!

@Lob Rockster: what is your typical fine profile (how fast, how often?)
