To put this in perspective, a car going highway speeds of 60 mi/h that travels for 24 hours will travel 1,440 miles, or approximately 500,000 times the car's length.

By contrast, this molecule is 3 nm long and traveled 1 micron in 24 hours, or approximately 300 times the molecule's length -- that is, about four orders of magnitude slower than the car given its length.
