+Funzioni
+============
+
+Note a riguardo delle funzioni.
+
+Domande
+---------
+
+La funzione forwardB / forwardA accetta una parametro tramite overloading:
+
+1. Se il parametro non viene passato da dove viene pescato?
+2. Si potrebbe fare la stessa cosa con un valore di default?
+2.1 Con quali differenze?
+
+3 La funzione composita drive pero' non accetta nessun parametro, implementare
+la possibilita' che accetti la velocita' come argomento.
