I had to take my car for an MOT test today, so left it at the garage and walked about a mile or so home to wait for the call to collect it again. Near where I live is a little hump-back bridge over the railway. It is often the scene of many a road rage scene. The road narrows just before the bridge on either side so that the road over the bridge is just one-car width. There is a road sign denoting who has priority to cross, should two cars arrive at once from opposite directions. However because of the rise of the hump, it is often quite difficult to see who is coming from the opposite direction.

However, some people don't put their brain into gear when they approach that bridge and use the priority arrow to mean carte blanche for them to go across the bridge without using any other consideration for anyone else. Even if someone from the red-arrow direction is three quarters of the way across the bridge before white arrow car comes hurtling along at great speed, white arrow car will more often than not force red-arrow car backwards three-quarters over the Bridge to their original start point!
At peak times, such as rush-hour or school-run times, it can get quite hairy, as people just don't use their heads. There are often arguments, gestures and I have even seen the occasional physical fight. Confrontations have happened to me in my car several times (quite recently I was red-arrow car going happily across the bridge with nothing in sight at all on the other side, when white-arrow car came hurtling along well over the 30 mph he should have been travelling at, in a souped-up, open-top Porsche and forced me three-quarters of the way backwards. My comments were unprintable!) If I had more time I would sit it out or even call the police, as in fact I did once before when Greg was still alive and sat beside me for moral support. (The police's view by the way is that people should use common sense when approaching the bridge and not take the sign too literally).
It happened again today, as I walked over that bridge on my way back from the garage. A young woman in a VW Golf was white-arrow car trying to force some middle-aged man in red-arrow car three-quarters of the way backwards over the bridge. He remained cool, got out of his car, still three-quarters over (and blocking) the bridge, strode purposefully towards her car and said something to her. I was out of earshot so could not hear what he said, but behind each of the two opposing cars a line of other cars was forming, tooting and honking their horns. The man then threw up his arms in mock horror, returned to his car and decided to back up over the bridge (as did all the cars following him), while white-arrow woman revved her engine and then proceeded to sail ceremoniously past him with a self-satisfied smirk on her face. I felt the sudden urge to tap my forehead with my finger at her as she passed me, to indicate what I thought of her. I don't wish her any harm, but can only hope that in the meantime a big pothole has swallowed her up.
Yes, the sign indicates who has priority if you both reach the bridge at the same time and there is any doubt about it, but it does not require you to leave your brain behind and force backwards someone who is already three-quarters of the way across, just because you technically have priority and arrived well after them. I despair of the human race sometimes.
Oh yeah.... my aged car passed it's MOT for another year. Put the flags out!
