Yeah, it's interesting.
On threads where kids have to go to a far away school due to SEN, the idea that parents ought to pay for transport seems to be overwhelmingly rejected. Or that they should drive them, or change work arrangements to do so.
The fact that she was in private school and isn't now is not relevant from what I can see. The whole tax is on the basis that supposedly private education is a luxury, and we want to make it more difficult for people to access in order to level the playing field.
So it has worked, this child is now in public school - why wouldn't the parents get all the same provision for transport as anyone else?
