It means that Amazon/Fed Ex/UPS drivers give NO F*CKS whatsoever and are currently the craziest drivers on the road. Earlier today, saw an Amazon driver (in a U-Haul, duh) run up onto a curb at 35 mph in a subdivision coming my way - while rushing around looking at his phone, of course.
On a related note, U-Haul must have their entire fleet rented out to Amazon drivers right now. Pic not mine.
