I watched a bit of her interview on LBC, which I would recommend avoiding as she comes across as a massively entitled self publicising arrogant nobber, and she was complaining that she couldn't do her job any more which involved helping people with ADHD fill out forms and such.
Now, far be it from me to diagnose at a distance, and I'm aware this is kind of personal but as somebody who is autistic and possibly ADHD, I have... opinions.
Firstly, don't use disabled people like that to try to gain sympathy. That's downright offensive. Secondly I'm not sure she's of the temperament to be teaching anybody life skills, let alone potentially vulnerable people who may struggle with what society deems 'normal' behaviour. She's a really bad role model. Thirdly, what's her reason for doing this work? Is there history? Part of getting to grips with my neurodivergent nature, and this I think is a good exercise no matter what your neurotype, was looking at my behaviour and my emotions, both past and present. Looking at my triggers and my reactions to certain stimuli and how they impacted on others as well as my own mental state. She's been triggered here clearly and responded badly, maybe I'm barking up the wrong tree but it all seems horribly familiar in a way.
As I've mentioned on the main forum, I used to be one of those annoying entitled shouty cyclists, but I had a good think about what I was doing and why, and I calmed myself right down. Maybe this driver could do with having a sit down and a look at herself, a proper look, and figure out why she reacted the way she did and what she could do to change and support herself to ensure that it's unlikely to happen again. That won't happen of course until she lets her guard down, drops the entitlement and accepts that what she did was inappropriate, but I can't help feeling that there's something there that can be worked on, if only she had the inclination to do so.
