In the presented setup: of course, the whole race was won with the described molecule by using the explained procedure. I myself directed the molecule across a Ag(111) surface by repeatedly applying small electric fields to the molecule. ;)
If it is hard to believe, have a look in the Nature Nanotechnology Paper and the whole incredible documentation of the NanoCar Race Event. There are so many broadcasted interviews, videos and also written reports in scientific and even non-scientific journals that can be found.
Also many interviews with the corresponding professors, chemists and pilots, who developed, synthesized and drove the molecules can be found for example on BBC Click, CBC quirks, NPR, the official NanoCar Race YouTube Channel and there is even the video of the win of our molecule.
Have a look and enjoy!

PS: Keep in mind that electric fields are much more powerful on a molecular scale than for example gravitational forces.
