I should think that rather more arrive by car and then use their
passes for a free trip to and from the city centre on the
park-and-ride buses - that's certainly how I use my own Freedom Pass,
given the cost and difficulty of parking in central Cambridge all day.

How far away from Cambridge do you live,

"Freedom pass" means that I must be a resident of a London borough.

and to what extent do you define yourself as a "tourist" when visiting?

I generally go there on academic business - but the National Bus Pass
scheme doesn't differentiate, providing that I don't need a Cambridge
bus before 9.30am on a weekday.

I'm sure there are some - although tourists are perhaps less likely to
use P&R than shoppers from Scambs, being less familiar with the system.

Possibly, although Cambridge P&R is well advertised - and drivers who
ignore the signs often regret it.

I imagine that there is also considerable use of the National Bus Pass
from people arriving by train, as the station is a long walk from the
city centre.

And are these tourists just "up for the day", or staying locally.

They have to be day-trippers to use the Park and Ride car parks. Of
course, being only an hour or so from London makes Cambridge a popular
destination for day trippers.
