I know plenty of people who are staying home not because they're worried about COVID, but more because they've come to enjoy the seclusion and convenience of ordering delivery all the time.
(I don't mean takeaway food - though it's certainly 'normal' among certain demographics.. - just groceries, Amazon, etc.)
In large sections of the US, I am guessing like 90% of the country it is almost impossible to survive without a car, like you literally will end up homeless without an automobile and I am not exaggerating.
But I suppose same would stand to compare picking up a takeaway in person vs. having it delivered. (i.e. if that's what I ate, I would almost certainly have it delivered.)
