Apparently, there's a driving etiquette rule in Poland where if you want to overtake on a two lane road you just drive confidently down the middle of the road and people going either direction just move out of the way.
@BertieBotts A version of this exists in Britain, or used to when I drove in Harlow, Essex, in 1985. There were roads leading to and from the town centre that were three lanes. The outside lanes were one-way so whichever way you were going, you would drive on the left. The middle one was meant as an optional overtaking lane where you would take the opportunity to pass one or two slow-moving vehicles and then slot in to let the people coming the other way to have their turn. The system was well-intentioned and designed to make it easier in the post-War spirit of New Towns but like much of the Highway Code, depended on courtesy and people behaving themselves or just knowing what to do.
The reality was that turbo nutter Essex bastards in Ford XR3is would put the pedal to the metal and dare all comers in the middle lane.
I'd only just passed my test so never chanced it in my Mini 1000. When I became a more competent driver in a more powerful car I still didn't want to chance it. Life is quite literally too short.
Another white knuckle ride at the time was the Beckton Alps flyover on the A13 in London, E6, between Essex and East London. There was a tidal flow where in the morning both lanes were westbound because that was the way the weight of traffic was going, and about 4pm it was reversed and the two lanes went eastbound.
That was a good idea except people forgot. I worked on a local newspaper round there and there would be accidents every day and some of them were fatal. But it still carried on for a long time until someone in authority realised it was a really stupid idea to let people decide for themselves where to drive and interpret Highway Code rules.
It's the same thing as people on here bleating: "The Highway Code says it's your right of way/priority" and looking at a wrecking crew clearing away the remains of a car that's been hit by a lorry going the wrong way and toppled 30ft off a flyover.
I believe it is now westbound only but I haven't been that way in years and wouldn't be surprised if it had been pulled down or fallen down because it was a rickety thing that looked like it had been built by Alec Guinness in Bridge Over The River Kwai.
Because of my special local newspaper knowledge I never used it and queued at the lights below because it was safer though there was always the fear of falling debris at that junction. We take our chances.
I have to say that Harlow and many other New Towns like Milton Keynes built after the Second World War are brilliant for learning how to negotiate roundabouts. They had loads of roundabouts instead of lights in order to facilitate traffic flow but it only works if you know when to go and it is frustrating when drivers don't understand roundabouts.
But I do and later on I could handle the feared Hangar Lane Gyratory in West London; Hyde Park Corner and Elephant and Castle in south London - all four lanes - with ease. I've never tried Spaghetti Junction in Birmingham but I bet I could do it.
I also like the bit where you merge from the left at 70mph from the M4 to the M5 at Cribbs Causeway going west at Bristol. It is like a ballet and as many times as I've done it, no one has ever got it wrong or slammed on their brakes. Going east is a little easier but that might be because I do it on a Sunday afternoon when traffic is lighter than Friday night. Maybe the OP and some other posters should try it. Or perhaps not.
