Be Vigilant When Driving
If you plan on driving in Greece, this is something you should be aware of. The roads are dangerous, and driving is probably not something you're used to. Indeed, most travel writers advise against driving in Greece if at all feasible.
If you're driving, be sure you're paying attention to the road and staying within the speed limit. You simply cannot afford to make any errors! Travelers on several Greek islands just walk from village to hamlet. Of course, this is dependent on their size. Buses and other forms of public transportation are also available.
You should be aware that Greeks, particularly in Athens, drive aggressively. If you plan on renting an automobile, always exercise caution. Outside of the city, the situation is a little better, but proceed with caution. When driving, motorcycles will not stay behind you and may frequently zigzag, while other drivers may overtake you on the left or right. As a result, be cautious and avoid driving downtown Athens; however, you should be alright on the islands and elsewhere.
