I would not say I trust it any more, but I use S&T because at least you can sit down with the laptop some time before a trip and work through the route and check it for mistakes, (both its and yours). You can easily re-route it if you don't care for the route it has selected for some reason. Setting the options for "fastest" vs "shortest" makes a difference. Shortest will tend to take you through side streets and back roads. Also setting road type preferences to favour major roads will help keep you out of the boonies. When all is said and done, they are just dumb computers, and "garbage in = garbage out" still rules. In spite of that, we still like to have it with us to show us where we are, and there have been several times when it has saved out bacon when we made a wrong turn somewhere or had a sudden change of travel plans.
