Bicycling should be pushed (and frankly, at this point forced) by the government. Loads of car infrastructure should be tore up and replace with cycling infrastructure. Cities should change those dead suburbs into places for people by making small modifications. Allow multi purpose buildings, allow smaller shops and restaurants there, tear up the ultra wide roads and replace them with small single direction roads for cars and add superb walking and cycling infrastructure with more than enought space left for trees that give nice shade...

Oh one can dream...
