Ok, my turn (this is fun...
):
1. Implementation of techniques to slow car traffic down to allow peds and cyclists to use the streets. So... not wider streets...as Machka's wants, but possibly even narrower streets.
2. An education program geared to drivers and cyclists, with the intent of getting more cyclists on the roads.
3. A public transportation system where either bike or walking would provide the"last mile". So buses or trains would either allow bikes on board or secure parking stations would be provided at each central station.
