Based in Bergamo,living in Lugano and home every night?
Well well....my navigation system says it's 120km/1hour20mins but it doesn't know you have to drive around Milan on the infamous "tangenziale" (the big ring road around the city) and the A4 (the busiest chunk of italian highway).
That can pretty easily and unexpectedly become a nighmare trip....especially if you have to do it before and after a 4 legs duty day.
