&gt; Electric boards clearly shouldn&#x27;t be on sidewalks, same as bikes.<p>Regarding bikes, it depends entirely on where you live.  If you are in an urban area, where the sidewalks are crowded, and cars can&#x27;t get up to high speed before the next stoplight, then certainly bikes should be on the street.  If you are in a suburban area, where sidewalks are empty and cars travel at easily twice your maximum speed, then the streets are not safe for biking.
