Thank you. Your chart is interesting and useful in its thread.
I should have clarified. There was discussion in another thread about why Canada has closed its borders to USian auto traffic from March 2020 (and is still closed through end November). It was because USians who were under lockdown / restrictions had shrugged and crossed a line on a map to a place where the barbershop / cinema / lottery outlet / malls (etc.) were still open.
Canada and most of Europe have made their anti-virus plans at the national level, with some local (name removed by moderator)ut (and local kibbitzing). The USA has operated at the local level, with some national (name removed by moderator)ut (and national kibbitzing). So that’s why I posted a map comparing the neighboring nations.
It’s less likely that USians will jet to Europe to do their shopping; it’s mostly about what people are doing within driving distance.
