far from coast? less than 200km is far for you? hmm
Yes. 200 km is a very large distance. Especially in the Sahara desert where there are no roads or even isolated tracks. Even the Egyptian military uses helicopters to get its personal to the Bir Tawil. How do you expect the pirates to get there. Also, given the naval patrols being conducted by the navies of Egypt and Saudi Arabia in the Red sea, I don't find it possible for the Somali pirates to reach anywhere near that area.
It's not really that desert of an area, there is even a national park around near by, the region is between the river Nile and sea shore, while some of it is located in deserted from the sea to the Bir Tawil area is far from being all desert, and you think pirates/separatists/terrorist in the region uses sport cars? it's pickup trucks and they know very well the region. Ask AQMI how they manage to move around in the Sahara between Algeria, Mali, Libya, Sudan. As how to expect pirates despite the tight surveillance (btw there are even US destroyers in the area to help) then maybe you should check the recent ships they managed to take over in recent years despite all that
