decosta? >> i would like the experts to listen to me on this very carefully. first of all, we need an analysis of our own roads. we have too many hills in san francisco. i'm not saying this is a sidebar conversation that is to the public. that's the least you can do. it's interfering with my deliberation. absolutely, so we have this issue of the hills in san francisco. and while we talk about bicycling which i favor, we need to do an analysis of certain routes where the majority of the routes is level. now, i was in bleen not along ago and they do a really good job there. not only having bicycle hubs, but bicycle lanes over long stances -- distances. just like the gentleman was saying, if you are allowed a bicycle is it just to go around the park or are you going to use it in a very sustain able way. now, i also want an analysis of the foot print. if you are using a bicycle to reduce the carbon foot print and go on building and pollute san francisco, we need to do animals -- analysis about that. we need to go deep into these issues rather than having a sidebar conversations while someone come here to talk. thank you very much. >> anymore public commen
