There is an overtaking button in the Plus 4 too. It is the big round one in the middle of the steering wheel
Ahh: Italian style of driving
Somehow the word "button" dropped out.
In Italian one of the terms used for a car horn is "Avvitatore acustico".
I remember quite good a motorcycle trip through Italy about 30 years ago.
On a winding route with a few villages, I was overtaken by a 70-year-old man in a very old Opel Kadett (Vauxhall) (even then). I tried to keep up - the driver drove in front of me through all the villages, honking loudly. I was only driving a HONDA CX500 with 50 hp, but the power should have been enough... After a while I gave up - it was just too dangerous - and my ears hurt from the constant honking
2005 4/4 1800ccm Duratec and a lot of HONDA CX500.......
