driving when not using their own vehicle. My own insurance used to
cover driving other vehicles (but not for damage to that other
vehicle) but that feature was dropped about 15-20y ago.

Mine still does.

Mine too.

Most UK car insurance policies will cover driving someone else's car
(and always have. But it's very likely to be third party damage claims
only.

It is alleged that when insurance companies assess the risk for a
driver, one of the reasons for asking their occupation, and having
different tariffs, is because there are correlations between certain
occupations and the likelihood of borrowing other people's cars (and
causing havoc).
