I've not done any really tough land borders while driving myself but none were that stringent. No one has ever been interested in my drivers license at a border. Had some interesting reactions at routine checkpoints in South Africa, Malawi, and Tanzania though since it's Japanese and they can't read it. But even then no passport check and didn't ask for international permit.

Germany to Czech Republic (pre-Schengen), wasn't even interested in my passport, waved past. German registered car, also no interest in the cars papers.

Czech Rep to Poland, think they glanced at my photo page of my passport, no stamp.

Poland to Germany, had to ask for a stamp there for travel memories, took a few mins as there clearly rarely use them. Again no interest in the car.

Spain to Andorra, didn't look at my passport. Andorra to France, no stamp but wanted to unzip my luggage. Spain registered car, no interest in papers.

South Africa to Swaziland and back into SA. Zero interest in car other than paying the Swazi highway tax. Passport stamps only. SA registered car, papers not checked on either border.

Everywhere else was just walking across (dozens of times HK to China and a lot in Africa like this) where no one cared much and visas issued promptly where applicable.
