I'd like to know what the previous driver was doing, because this is a doozy.
On my way north from Morgantown to Pittsburgh, Waze navigation tells me to exit I-79 north at Waynesburg, and immediately get back on I-79 *south*. Then it wants me to do a u-turn at the next emergency turn-off and continue north on I-79 again.
All the roads in that sequence have already been munched, so it is my assumption that someone had Waze running when they had more of an adventure than anyone had intended. I wonder if the PA State Troopers had anything to do with that.
