The videos show them as small elevated platforms reachable by a single flight of stairs. Would be low cost as depicted but I see no way that it would get safety or ADA approval in that form. Add an elevator and it gets much more complicated. Have them dip down all the way to street level and there's a much bigger footprint required.
