A little tip for anyone driving in Switzerland: don't ever, ever speed (or get caught speeding). Unlike in Australia, don't assume you'll never get caught, because you can and will here.
Speeding fines are really stiff here, and often are based on your income (e.g. x days income as a fine); as a tourist, it'd likely be a flat fine of some sorts (since obviously it's too difficult to assess your wages and thus a fine if you don't earn a Swiss income). You can appeal your fine to a court but if you do so, you will need to pay costs (unless you are fully exonerated, perhaps) and the fine limits that normally apply in your first instance do not apply in court, so your fine can increase.
In some cases, you can be imprisoned (or given a suspended prison sentence) for high speeding violations.
Speeding can be considered a criminal offence in Switzerland and you can have a warrant issued for arrest in most other countries.
No, I didn't drive or the like, but I just read a thread on an expat forum talking about speeding in Switzerland. They don't mess around here.
