Often times I rent a car when I travel. However in some countries locals do not follow the signs / speed limits / etc. While in other counties it would be costly to go even 10km/h above the limit. There are even countries which do not fine until you go 20+km/h above the limit by law.
Also in some countries it's common to bribe the police, while in others you probably will be out to jail for that.
Is there any resource where I can lookup all these little nuances before I hit the road?
