Robert Carlso Author of ‘The Miniature Railroad’ built an amazing Hot Wheel track with the help of some friends. It is every little boys dream to build the most longest and coolest track ever. With the help of a GoPro Robert and the team were able to capture the journey from the toy car’s point-of-view. The Hot Wheel car goes through backyards, hills and even into a pool. The whole thing was powered by the help of gravity, and no electric was used.
