I’m sure you could get someone to do it, ask motability to advertise in their magazine.
Dont think you would need all the other stuff, many YouTube videos are shot on an Iphone.
I just don’t think anyone is considering disabled when designing charging points, charger location on the car, disabled charging spaces, help at the charging points for those who can’t easily get out their car, booking slots for charging at disabled bays so you don’t turn up and have to wait hours to charge etc.
The disabled ev drivers need a warrior and I think that could be you Julie.
Please have a think about it and if you decide to take it further Robert Llewellyn of “fully charged” would be the first person I would contact.
