In summer I want to travel a bit about Western Europe. I think I would start with Austria and Germany.
Is it possible to (easily?) find place, where I can just sleep in a car, a place that is free (or considerably cheaper than staying in hostels or motels), but above all, safe to stay there? Where nobody would mind me and bother me there.
I would just go in a normal car, not RV or anything. A station wagon type car, and with mattress in the back makes for pretty comfortable sleeping.
