answer:If I’m traveling 70+ mph on the interstate then I can do five miles. Been there and done that many times. If I’m stuck in traffic going nowhere, then I’ll stop and use the side of the road the best way I can (even if I’m just standing behind an open passenger side door on the right side of the road). Been there and done that, too. Generally I try to plan a little better, though. These urges don’t come “from nowhere” after all.
