I also ride my bikes the last 2 years without a license, however I've always drove with safety, wearing my gear always and driving calmly (When on public road with traffic... :x) I've been stopped couple of times, but none of them I was arrested or fined; Reason is that the greek police doesn't really harm those who drive under safety and obey the speed limits, if you wear a helmet and you drive normally you'll never get in shit. I've had couple of friends who have been arrested, send to trial or fined for not wearing a helmet... or being envolved into MVA's just because they drive aggressive like delivery..
On top of that, I'm having my driving examination for car license in 5 days, and in 12 days I will also have the motorcycle(125cc) license examinations.
