My FiL was one of those
Not kiddin', coming down the one lane slip lane onto the M53 yesterday at the Moreton spur...if you know it, which you should, it's long by comparison anyway, and this fossil was dawdling along at an indicated 35 miles per bloody piggin life wasting hour.
Totally oblivious to the 10 vehicle crawling traffic jam behind him.
Stupid old bastard shouldn't even be on the road if he can't make REASONABLE progress ffs.
His seemingly compulsary flat cap was actually white btw. An extreme danger signal.
