I was a legal temporary foreign resident alien in several foreign nations, and obtained permits to drive a privately owned vehicle in those nations.
First, I had to provide proof of drivers training, and meet insurance and vehicle inspection requirements of the permitting nation.
The primary sticking point was documenting my legal non-citizen “guest” status, in order to procure my license to drive.
That was in Western Europe, who have what is termed an “International” drivers license.
It is an embossed piece of paper, with no picture, but combined with all my other required photo-documentated proof of personal identification, allowed me to legally drive in several foreign nations...
Most USA citizens refrain from traveling to foreign nations, primarily due to lack of interest, or lack of funds.
Why would we?
It takes a lifetime to tour the USA.
If I had lots of money, I would spend the rest of my lifetime touring both USA and the Euro continent, having been privileged to tour a bit of both. Not to mention a six month side trip to Israel.
I was just thinking tonight, how long and expensive a Journeys of St. Paul tour would be. We're talking a lot of walking and boat trips. :)
If I'm still healthy enough 15 years from now, and the IRA's hold up, and the world hasn't gone completely to hell, it's travel time. God willing.
