Not very good examples:
--When someone falls in front of your house it is your responsibility (not an 'act of god' as it says in english law) - you can get sued for that.
--As an adult you can't ride on the sidewalks - if you want to, that particular piece of sidewalk has to be marked as a bicycle path (which makes sense considering the high difference in speed between pedestrians and cyclists). In reality nobody cares about bicycle paths so you get an obstacle course of trash cans, cars (and their doors) and pedestrians...
