Note that very few automobiles are equipped with toilets or washroom facilities. ET3 capsules operate as cars on a freeway so when toilets and washrooms are needed the capsule will never be further than about 15 min from an access portal with such facilities. An option is removable cushion with a plastic bag lined receptacle for emergency use. Some privacy can be availed with a pull down screen between the seats. Not a replacement for a toilet, but better than nothing if sudden urgency strikes.
