Have you experienced this before, urination on the highway in traffic jam and no toilet far and wide? In this case (only for men) I have a small, old warm bottle of rubber lying under the driver’s seat. My wife kept it; once belonged to the children. In it you can easily drain water. Volume of the bottle is 800 ml. That should be enough for the first. Close with the screw cap. Then nothing runs out. Don’t fold, take hardly any space and i A friend of mine has an empty granini bottle in the car. What kind of practical ideas do you have? We used to have a VW Multivan. There was always a small 5 liter bucket in it for emergencies. Women could use it. (was also used when the AB toilets were very dirty at rest places) Greeting from the sailboat man
