To answer other PP questions, no, France hasn't locked down this autumn/winter, neither have Spain or Italy and similar countries, despite a sharp increase in cases.
I think in general they have less rules, but extremely harsh consequences if you break the few rules that do exist. Curfew is strictly enforced. After months and months of only leaving their house with documents showing where they were going/for how long, and being fined if they failed to produce the required paperwork, everyone is taking it seriously.
Where I'm from in Spain, there is a Fri 3pm-Mon 6am local lockdown every week. You cannot leave your town during those 3 days. Every single Friday evening, without fail, my dad is stopped on the main road coming into town on his way back from work, and questioned. He needs to show several documents as proof of address, the police stop and question every. single. car. Every weekend.
My mum told me the other day about her friend who wasn't allowed to leave the supermarket for 3 hours because the police were called to do a check on a person whose neighbour was convinced they were Covid-positive. They called the local health authorities who gave them a list of all current positive cases in the town. The police then checked every single person's identity cards. This whole thing took hours and happens very often - the police have the right to check, and they do. Turns out there were 22 positive people in the shop (this is not normal there btw). They were all issued huge fines. I have absolutely NO doubt this is also happening in the UK, and in other places. But it's easier to not get caught. Selfish idiots think they can double mask and just pop down to the shop, they won't infect anyone. That's how Covid spreads.
