My Unu/Black Tea (no Vespa) do have honks, but they’re quite whimpy, and the Viennese will scream extra bloody murder at you for honks as well, especially if they’re the ones standing foolishly in the middle of the road with their mobile phone plastered to their faces, and you’ve just added a new black line in the road, braking not to hit them ..

I keep thinking I should upgrade my honk to make it beefier (although honk usage can get you a traffic ticket in Vienna), but I want to experiment with the helmet whistle a bit more, just to see if its effective ..
