In Milano lots of people commute to work on motorcycles.
Lest you assume everyone is sporting a Vespa and trailing a scarf in the wind, the typical moto is a medium sized bike like shown below... with an occasional Vespa or Harley thrown in to spice things up.
This moto-commitment seems to transcend all types of weather, much like the US Postal service or Santa.
An interesting piece of gear that I’ve not seen in the US is a heavy “skirt” laid over the lap and shoes, and often tucked around the legs. I think this serves to keep your legs clean during your ride year round, and serves as extra protection again the cold and rain.
And often they simply drive up onto the sidewalk and park.
