I once travelled in my car for couple days and the hardest part for me was staying fresh in terms of hygiene, I can not feel good unless I have a shower in the morning, bath twice a week and brushing teeth/shaving daily, I can not imagine doing that while in a car or in a public restroom, I guess I just need a private space for that. It is actually the main reason why I can't relate to homeless people, most of them have a horrible personal hygiene and are very unappealing to talk to because of that.
