I am so sorry that it's this way in the Uk.
I can confirm that this is also true of both my daughters' schools
First of all it's not a one way system apart from in the playground. The steps and paths are two way and there's a maximum of a metre available to distance. People are dropping off early and picking up late or just arriving whenever. Hugging other people's kids, coming right up to others to chat and generally behaving like normal
A small minority of parents, including me, are wearing masks (I'm doing it largely to remind people that we're in the middle of a pandemic - I've noticed it does seem to help people to remember to SD a bit). But otherwise you wouldn't know it was any different to March. If they're all behaving like this in the rest of their lives.....
Children of CV parents should in my opinion - at a minimum - be provided with a computer for home learning and support to stay at home if that is their family's decision / if local infection rates rise etc.
It would also be nice if the government provided enough money for schools to actually properly SD in school (using other venues, more staff, blended learning, whatever it takes), which would also reduce risk and mean that the children of vulnerable parents were able to be in school with more confidence.
