But in the same respect Mclaren Mercedes was sponsored by "WEST" also a tobacco manufacturer was allowed to run the"WEST" livery because no one else in the United States is sponsored by "WEST". I believe the same is true for "Lucky Strike" which sponsored Honda and "Mild Seven" who sponsored Renault."
