It's a pretty robust logistics system. The tour lengths are 2-3 years. If your job demanded that you relocate to another continent for 3 years I think we'd all expect some relocation assistance.
True but providing a local vehicle pool might be a lot more sensible. That way vehicles are more innocuous and also meet the local requirements better. Think of the UK for example where they drive on the left. I've driven my Dutch car there and while it was possible with some stickers on the headlamps, it was a real PITA when trying to enter a parking garage because the ticket machine is on the other side.
