One thing to consider, is that whilst Oxford isn't particularly
great traffic wise, if your wife was to commute there and you lived
in London (or its outskirts), at least she'd be going against the
majority of the flow of traffic for a lot of the journey.
The killer, however, is the last four or five miles where she won't
be. And where to park??

I was sort of thinking she would catch the bus - live in Hillingdon or
similar, so he could catch the tube into London and she could get the
bus to Oxford.

That would avoid the need for driving, but at the expense(sic) of higher
housing prices.
