I know right you can't put every small city and road in the game XD I was just giving an idea about a possible connection!!! I can give you informations about trafic rules in Portugal when the time is right (I know you're still far away from it and I get it perfectly!!!) and I could also try the editor when I get time to.
PS: I seriouslly doubt anyone else has the same passion for roads and driving than we Iberians (Portuguese and Spaniards)!!!
