I knew a guy who made IP of the year at Rucker who the next month after the award taxied a Blackhawk into a telephone pole at an FBO. Actually felt bad for the guy as it was a tight-ish area and he was actually a really great guy so I hated for it to happen to him versus one of the other bozo, grouchy IP's that needed to retire 10-20 years ago.
Unfortunately in multi-crew aircraft there's no excuse when it comes to ground taxi accidents. At least one person can hop out and go ground-guide.
