I have a friend of mine that has horrible road rage. Fortunately for her, she has a friend like me that has figured out how to suppress that anger. What I am going to suggest her, is every time someone aggressively cuts her off without using their turn signals, is to a sing an America classical patriotic song, with the modification of one word. When she feels her temper is beginning to boil, I think she will be inspired to share the road by singing,

“This lane is your land, this lane is my lane
From the California to the New York island
From the Redwood Forest, to the gulf stream waters
This lane was made for you and me”
