First car to 3 million miles? (this guy taught at my jr. high school)

over the road truckdrivers run about 100,000- 120,000 miles per year.
why does he have to drive this car soo far? Is he an over the road car driver?
it's not easy either racking up all those miles, I know too, Ive got about 2 million miles OTR driving semi's and that took about 24 years (on and off).
That guy does not have a job! HE cant work, he doesnt have time to work, he has to drive his car!
