The Reddit user LordMackie left his trucking job after 1 year & 4 months. In this time he racked up a fair few miles on the clock.
The map he has created shows the most and least travelled areas. He said that he enjoyed the ride from coast-to-coast and also likes I80 route in summer & I40 in winter.
I came across this map on Reddit and thought it was interesting, you can read the full discussion here.
