Imagine what will happen if you get the flu. You're suddenly stuck in a tiny living space, on a street where you know no one, and can't leave the van for fear of discovery, at 3 in the morning. You're going to spend the night vomiting with only a tiny cassette toilet and what ever plastic bags you can scrounge up to hold it in, and if it's strong enough, you might be too weak to even drive.<p>Now go and read that site's health and hygiene, realize the owner never even considers this a possibility, and that his own van doesn't even include a cassette toilet. That he can only defecate during a store's business hours, and he uses a laundry bottle filled with bleach to pee into if he needs to urinate in the middle of the night.<p>You really want to listen to this guy?
