A thought occurred to me today... There are hardly any unmarked
crossroads left nowadays. Even tiny little country lanes are usually
provided with give way lines when they meet to establish priority at
junctions.

Why is it, then, that in one very common situation priority gets left
undefined by the HWC? I'm thinking of carriageways with 3 or more lanes.
If there are vehicles in L1 and L3, then there is no defined priority for
moving into L2. Quite frequently travelling on motorways, I see this
situation, where both cars make for L2 at the same time: one of them
usually notices and swerves back into its original lane.

Why not just establish priority, for example by saying that the car
moving back left always has priority? This would add clarity and remove
danger.

It's the L3 user that has brain disengaged when hanging lane in the blind
spot of someone in L1. It's easier to look ahead than behind.

Because, if they did, people would assume a right of way and just switch
lanes without looking. Also, hardly anyone reads the Highway Code.

Some things are best left to common sense. Most of the time, it works
just fine. Research has shown that confusion by design forces people to
think and actually improves safety.

Its certainly a danger, everybody must have started to move lanes just
as another car did the opposite. You cannot always rely on
anticipation to spot it and its one of the harder to things to see,
given it happens to your left or right rear. If its a danger because
its not spotted, I'm guessing telling drivers to priority will not
solve it?
