Just over a year ago, a suspected drunken driver heading the wrong way on Interstate 75 in Kentucky struck a vehicle carrying a family of five from Michigan. The crash killed three children, ages 7, 13 and 14; their parents; and the other driver.
Jonathan Stone, head of programs for research and advanced engineering at supplier giant Continental, knew the family that was killed.
Taking last year's tragedy and others like it to heart, Stone, 44, embarked on a passion project. He developed a roadside system capable of detecting wrong-way drivers and alerting others on the road of the impending risk.
