A bonus. I was able to park on site... as opposed to finding some side street.

I should explain. The "site" in Surrey is a large campus with a significant number of staff. It is a significant distance from the railway station, and has but a limited bus service. The consequence of this is that the vast majority of people have to drive. This results in there being significantly more cars than there are car parking places. As a result, if you don't get a place you are cast-out upon the streets.

This is all part of HMG's integrated transport and revenue plan. By not providing transport links, it forces you to use the car, increase taxation revenue through fuel consumption, speed camera, and parking fines.
