Are we all talking about this one:
(I can't see Twitter from this machine!)
If so, I agree, it is rather misleading on 1 & 2.
I do wish everyone jumping up-and-down about those 2 rules would actually read the ACTUAL HC, but it's hardly surprising when they don't :-/
On 2 it is very misleading, because it absolutely doesn't say you "should" do that. The actual wording is "You can ride two abreast and it can be safer to do so, particularly in larger groups or when accompanying children or less experienced riders".
On 1, I think it is only slightly misleading, because that does appear to be the "general" advice, with it saying there are 2 basic positions you should adopt, and that being the first one.
But there are numerous stories in the press which are just ridiculous - suggesting that the changes to the HC mean there are additional things for which you could be fined, for instance. The changes make no difference to the law, so no difference to what you can be fined for. They mainly just clarify existing guidance, and add a few new bits.
One example headline from the Sun says
"DID YOU KNOW?
Highway Code rule changes LIVE – New 2022 rules about roundabouts, junctions & car doors could land you huge £1k fine"
Or from the London Evening Standard:
"A new rule will see
drivers fined £1,000 if they open the door with the wrong hand, as the
Highway Code is updated."
And unfortunately, it isn't actually all that easy to read the ACTUAL changes until they are finally incorporated in the current HC.
There is a pdf of the changes
here, but that takes a bit of searching out, and quite often fails at the first attempt to load.
