Park and Ride services

It always puzzles me why some local authorities make it cheaper to park in the centres of busy cities than use Park and Ride services, when provided. Park and Ride services should be priced so that they are always the less expensive option otherwise why bother?

Park and Ride

Every Tuesday I drive into Cambridge (Newmarket Road Park and Ride) where I pick up the Park and Ride bus into Cambridge, where I attend my U3AC course called "Maps in the Computer Age". It is an excellent course with good supporting notes and links. Apart from the £1 to park, travel into the city is free as I have an OAP bus pass.
