I’ve driven around the Balkans a bit. Probably the craziest driving is in Belgrade. The easiest is in rural Slovenia. People generally always drive fast. They love it, like this moron who I assume is on the A1.
Driving fast is fine when you know where you’re going. When you’re a tourist, things get dicey. A map is necessary. I always had mine from Freytag & Berndt when I was driving and I was thankful for it. There are those who think that Google Maps technology trumps the age-old paper map though. For those interested in using it, you might want to think again as shown here and here for going between Dubrovnik and Mostar and Split and Dubrovnik. I know I like a ferry to Italy, how about you?
