Re: I'll never really understand...
It depends on his personal circumstances and also which countries he was offered... For the actual back-office staff on site, it isn't so glamorous as being in the pits or sitting and watching the race. All the time the cars are being prepped or are on the track, you are probably stuck in a hot and sticky trailer, making sure everything is working. No going to the hospitality and saying "page me if something goes wrong".
I was offered the choice of 2 travel opportunities in the early 90s, IT support for the team running the elections in war-torn Angola or war-torn Bosnia... I somehow managed to lose my passport.
The guys that did go to Angola were accused by the rebels of collusion with the regime and there was a running gun-battle to the airport to evacuate them... I'm so glad I lost my passport.
