It is definitely Freiburg. 30 min to the "Feldberg" by car. 45 min by car to Basel . You can connect with "meinfernbus" from Freiburg to Zurich, Stuttgart, Berlin, Friedrichshafen etc.
Speeding in Switzerland is not encouraged. e.g. 1 km/h to fast and you get a 40 CHF Fine .
30 km/h too fast and you might get sued in court...
