My ex was one of those fellows. After we had exited to get turned around the other way we were still going the other way. He wouldn't believe me that we were still going west even when I pointed out that we were still driving into the evening sun. Twenty miles later as we approached the next exit I spotted the signage that said west and asked if we were driving east why did the signage say this was xxx west? He finally conceded and we turned around and were only fifty miles from our original mistake. His mantra was I'm always right until you PROVE me wrong. Made for some interesting situations.
