It’s a Vespa trailing an Ape.
Spotted in Firenze in a hot traffic hour, 5:30pm, zigzagging between the cars lines just as if there is no trailer. This way they crossed half the town from Fortezza da Basso to Ponte dell’Indiano. The picture was shot in via di novoli, you can perceive the trailing cable (just a rope).
Long live D-I-Y !
