Not sure what's going on here, but this reads like 90s cosplay.
First off, GPS-guided trips had not yet eroded people's sense of direction because they did not yet exist.
Second of all, the (odd-numbered) interstate(s) that flow from Michigan to Florida are large and feature many prominently-placed, large signs with large, readable fonts. Even if you exit to a state road, those roads are littered with interstate signs for dozens of miles that will direct you back to the interstate, using words like "North" and "South" which are displayed in large bold lettering.
It's one thing to ignore all those signs because the voice in your Iphone is actively telling you a different thing. It's quite another for those signs and your paper map to be your only known sources of truth, and to steadfastly ignore all of them until you have to pull over and go to sleep.
In short, OP had an impressive lack of situational awareness/direction and is trying to play it off as a common burden of the olden times. It wasn't.
Edit for the "directionless" iphone-directed youngsters:
* Signs on the interstate in the 90s came with industrial lighting, as they do today. You can read them in the middle of the night
* Signs on state/county/municipal roads were painted to be highly readable even with the comparatively puny headlight strength of the 1990s
* This was certainly before the opioid epidemic and probably also before the heyday of meth. So shirtless guy was probably just a shirtless Kentuckian checking if OP was OK.
