Well, yes and no. I had fewer "close calls" with traffic in four weeks of touring in Japan than I did in four seconds of riding back on the Gold Coast after my return (that's right, four seconds.). I'd say that most of the time when you're touring, you're probably riding on quieter roads than when you're commuting (or in my case, you're dealing with more competent and considerate drivers when you're touring). When you're touring you also have more leeway to pick the hours you're on the road, which may not be an option when you're commuting, or trying to fit in "training rides" around the rest of your life.

Personally, I tend to fret more about missing transport connections or flights, and being stranded somewhere. I also worry about being robbed, although it's never actually happened to me. There have been occasions where I've worried about certain types of people visiting my campsite uninvited, but I have to admit that on some of those occasions I was camping in places I probably shouldn't have been. Other times, I guess it's just the usual basic annoyances like getting lost in an unfamilar town or city, or having some idiot in a commerical campground making noise late into the night when I'm trying to sleep.
