The difference between someones driveway and a road is not that big in Sweden (legaly)
In Sweden you have the allemansrätten (every mans right) which gives you the right to walk/cicle everywhere in the country as long as it isn't or looks like somebodies private yard/garden. So att the countryside you can use someones driveway to get where you want.
This doesn't apply for cars, but even then there are a lot of roads privatly owned or owned by a local organisation (a group of neighbours). If there isn't an explicit ban on motortraffic you can use these roads by car. A lot of these roads get a maintanance contribution of the state or municipality, and then they have to allow all traffic on the road.
I probably are the first car in a very long time on some of the roads I map, but it is great fun to explore them
