We are looking to increase our database of legal references for bike laws in the regions we currently have map data (PDX,SF,NYC and Chicago) as well as our planned expansion into Seattle, LA and Florida. If you know of any government open data projects that have this data available or are looking for developers to contribute in exchange for data access let us know.
Bike laws from as many states as we can find.
