>>1996043I'm inclined to say it doesn't exist. Skateboards, electric longboards, and bicycles are the main contenders imo. Skateboarding is worse than walking in too many situations (high traffic sidewalk, any road busier or faster than a quiet neighborhood street, rain, snow, hills) and the distance you can cover with them isn't very far, so the time difference compared to walking even in favorable conditions isn't worth the hassle. Electric longboards are great for (good weather) commuting, but the moment you have to walk around with one, it's a hassle. Similar situation with bicycles except they are immune to weather but cannot easily be taken on transit, indoors, and are generally even more of a hassle and basically like owning a car having to deal with parking and all that.
