There is a huge problem in Greece with fuel lacing (mixing it with inferior flamable liquids). This increases consumtion and destroys the engine (mainly the lambda sensors). Personally i use only 97-98 oct fuel (the mid grade) or above, simply because you can't even trust reputable gas stations, especially after the Ukraine-Russia war. The state (as usual) does next to nothing and you will never be compensated for any damages even if you have a receipt.
In Greece the person on the right has the right to pass .In roundabouts (in Greece) this is true unless it is stated otherwise. I believe that in the rest of the world permission has the one exiting the roundabout but it's different here.
