Frankly, I haven’t seen what a portable toilet for cars look like.  Is that a box or something?  I agree they can come in handy when you’re stuck in heavy traffic and you just got to go.  Well, I’ve known the situation and I was glad to have a nearly empty Coke bottle at the back.

The traffic in one of the freeways here was at a stand still for more than an hour and that bottle came in handy when I had to pee. I’m not about to spend money on something I will discard anytime.  I mean those bottles are everywhere and having one in the car can do the job. So my advice, don’t discard those bottles too soon.
