Um, auto explore has murdered me twice so far (ran out of air by running off on a tangent before I could stop it - on perma-death, of course.) Add in that it does not avoid terrain like black holes, acid, and cave-in traps means that you can get auto-mauled badly right before you get ambushed. Over all, it does a pretty good job, but when it fails it is usually fatal.
