The documentary correctly identified the overtaking, speed and lane-disrespect as the most important reasons for all the 22,000+ accidents that happen each year in Greece. And it did remind me how my brother wouldn't stay on his lane when we visited Athens last Summer. The reason for that is because all roads in our home in northern Greece are single-laned (one lane going towards one side, and one lane for the other side). Even if my brother is a very young person, he doesn't know how to behave on a multi-laned road. He doesn't know that he must stay on his lane instead of switching from one to another all the time for no good reason and without using the flash. Athenians are not much better either. So while we can say that Greeks are bad drivers, the conditions of the current roads have an effect in their performance too.
It was also nice to see my place in the US TV. They showed Ioannina and Metsovo, which are pretty close from where I am coming from and have visited a number of times.
