What would it take to get you to commute to work (or school) via bicycle?

There’s a survey in my region that I took today about this subject. It asked whether we commuted by bike and how far and how long and how else we used it and what we thought would be needed to make biking more attractive. There are also bike commutes to public transportation for those who live far away from work. You can bring your bike onto subways or put them on racks on the buses where I live.
