It is the sight of a police van that immediately jars. There it is, beneath the underpass, jutting out at a big, dangerous right-angle and causing problems for those who try to pass by.
You tell yourself this cannot be real. In the same underpass, just over two weeks earlier, the same kind of vehicle was parked in the same kind of way and caused chaos, leaving thousands of Liverpool fans terrified on what should have been one of the best nights of their lives.
But it is real, all right. It is a dreadful nuisance, leading to bottlenecks and delays.
