Mobility Element of PIP

When I read the members only guide to PIP, it states that difficulties in using public transport should be submitted as a reason for being unable to plan and follow a journey.
My wife is totally reliant on me driving her to anywhere either local or certainly distant. It does not cause her overwhelming psychological distress because I do all the planning and driving.
In the summation for her recent PIP assessment
the decision maker has stated that they "cannot consider awarding you PIP for any help you need for anything not covered by the daily living or mobility activities, including physical problems with public transport. She can not walk to the bus stop or stand and wait for a bus, she cannot lift her walking aid onto or off a bus, and is not confident enough to travel unaccompanied. She has a NOW pass which is unused because of the difficulties. Any comment or assistance.

Hello Gordon, thank you for your reply. Does the fact that her conditions although physical mean that even though I have to take her everywhere or it would quite frankly be impossible, and would without doubt cause overwhelming psychological distress not mean she should qualify. She is under a clinical psychologist at the pain clinic and also MINDS due to previous trauma, but they seem to deem this not significant.

Thank you once again Gordon. I can see the subtle difference and it is easier to comprehend their stand point. I will attempt a Mandatory reconsideration, took them to a tribunal for ESA and they backed down the week before the delayed hearing and gave her support group just for mobility without visiting any of the other incorrectly scored sections.
