Jase11,
Your comments about passengers, or lack of them, reminds me of a trip I did in late 1975. I drove this LHD Fiat bus from Istanbul to Delhi with a full load of passengers, roughly 4000 miles, where they alighted, or should I say, I tipped.

This motor was a seller, the owner asked me to run it up to Katmandu, Nepal where foreign vehicles could still be sold in those days. The Indian authourities had stopped this some years before, as had earlier, the Afghans. This sort of thing still went on at the time, but penalties if caught, made it not worth the risk just for a few thousand dollars.
Anyway, it was one of the best driving experiences I’ve had, a reasonably long distance drive in an empty large bus, not having to think about, or consider passengers. I managed to prolong the journey to a week, stopping where it suited me at night, sometimes sleeping across the back seats or in cheap hotels.
The photo was taken in Pokhra, west Nepal, leaving an easy drive east to Katmandu through the Himalayan foothills the next day. It took about five days to find a buyer, set up the sale and so on for the owner, then I flew out to Singapore, enjoyed a week there before flying on to Perth in Western Australia to get a proper job.

Apologies for going Off Topic, I almost forgot about Foreign Truckers. If you are wanting the worst, then in my experience I would say the Turks, the Tahir Pass in eastern Turkey was a good place to see them at their worst. They were closely followed by Indians. Some of the long distance Afghan truck drivers would refuse to use any form of lights. The long distance Iranian drivers running to Europe, I thought were very good.

I photographed this Afghan truck between Kandahar and Kabul in 1968, on another trip. These vehicles covered vast distances, and would never depart from anywhere until they were overloaded.
But all this was a long time ago, I doubt if anything is very different.
