caravanners should only be allowed on the roads at night.

Public highway. The clue is in the title.

Add to that gypos in those crazy horse and traps!

There is no place for horses on the roads today.

Get them regularly on the edge of the village and have to be mindful as can't see round the bendy bits.

Ok, they always acknowledge the courtesy, but not all drivers are like me!

Good friend of my son's lost his mother in the place I'm talking about. She was leading a horse with young daughter on.
The horse bolted and she was killed.

A short while later her husband killed himself.

a few years previous, a girl was riding on the bendy narrow lanes, in a different village, and she was hit by a van driver.
Both her and the horse were killed.

Here you go. This didn't take much finding and there is more of it!

They don't even stop for the police here.

buses also

women drivers

how about no L drivers 7-9.30 & 4-6.30,that should help as well.

This reminded me of a story my dad told me.  He was cycling in Scotland during the holiday season.  On his way to Crieff there were roadworks and a temporary set of traffic lights, such that traffic could only go in one direction whilst the traffic in the other direction had to sit and wait.  The road was curved such that you couldn't see the traffic lights at each end.  It was also quite narrow with a cliff drop such that when he set off the caravan behind him couldn't overtake him.  It was also quite windy and he was cycling into the wind.  At about halfway he saw another caravan heading towards him.  As the caravan came to a halt he cycled past.  It was another 12 miles to Crieff and it was a slog into the wind.  Yet during that entire journey he wasn't passed by another car the whole way.

The problem on the roads is not caravans, lorries, gypsies etc its the sheer amount of traffic on our roads. When you've got past the caravan there's always something else in front or stuff coming the other way to stop you overtaking.
The rest of northern europe saw  the problem in the 70s and 80s and took means to discourage a lot of motorised traffic by providing and encouraging other means of transport. Our government however persists with the old unsustainable model and simply builds more and bigger roads to accommodate more and more vehicles. When the new roads get clogged up it builds more roads and so on................
One small example.
In Denmark in some of the more rural areas there are good regular cheap buses into nearby towns. Behind the bus stops are secure areas to leave bikes. So people cycle to the bus stop, leave the bike locked up and get the bus into town thus saving a lot of unneccesary car journeys.

In London....half the drivers are foreign....I doubt whether most they have adequate insurance....any problems and they will naff off to Europe and my insurance will have to cough up.

Bix nailed it. Public highway, which you have to share with other people. Seems simple enough to me.
