I do not feel compelled to encourage anyone to do anything..I am happy to share my joy in my love of cycling to others...
Urban density would be a real hassle..Think I would pick and choose my city based on that concern.If the roads are unsafe, no amount of encouragement will work..
My sell ? woud be for a positive health change and cycle/commuting is far less stressful than driving on crowded roads.Next would be saving the planet from an energy melt down.
