Cruising Blind (2024x12)


:

Cruise control was invented in Hagerstown, Indiana by a blind engineer named Ralph Teetor. He lost his sight at the age of 5 due to an injury. He came up with the idea after riding with someone who would speed up and slow down a lot. Ralph developed the Speed-o-Stat, that would later become what we call cruise control, to solve this problem.
