Thanks for the VRN etc. From what I can see, personal details have to be entered as part of the challenge process before evidence can be viewed.
Can't see a win here IMO.
The driver was collecting a student from college. 'Boarding' as a statutory defence is IMO very, very narrow; even taxi drivers have to 'drive round the block' if a passenger is not waiting and cannot simply wait for them to turn up.
But you* might as well submit a challenge within the 14-day period, there might be a procedural impropriety waiting in the wings.
* who's who here? You refer to the driver in the third person, but ultimately liability lies with the registered keeper. Who is the RK and is the vehicle leased/hired etc?
