Gossipwitch, I don't think it's a case of 'not being bothered'.
If your the child in your example cannot walk safely to school, or the parent cannot get them both to school at the same time, it is likely they would still qualify for transport.
In fact, the FAQs in the link you gave states:
"Clarifying entitlement of SEN children from families where a parent/carer has a disability, and may therefore require travel assistance with their journey to and from school.
This could mean that irrespective of the distance from school, a pupil may still be entitled to travel assistance if their parent/carer has a disability."
ie. you would still get assistance.
"Introducing a charge to parents/carers where the Local Authority arranges travel assistance for students attending Post-16 provision irrespective of where they attend education.
This could mean a charge being introduced as your contribution towards the full cost of providing travel assistance to school or college for your child. Presently this would equate to an annual charge of £240 for transport, which would help offset the local authority?s average cost of £3,880 per year for each student."
This would just bring SEN children to the same level as non-SEN children. There are many parents with NT children in exactly the same situation you describe, who struggle to pay £240 per year, but they have to. We shouldn't get dispensation for things that would affect us equally if our child was not diagnosed with an SEN, IMO.
"Who will be affected?
We expect that most SEN children and young people currently receiving travel assistance to and from school will continue to be offered travel assistance under the new proposals; however this depends on each individual's circumstances. "
I do think that a child who has pure SEN rather than SN, who has a statement of SEN, should not automatically get transport assistance. There won't be many of those, but the Council doesn't, to me, indicate that it thinks those proposals will affect big numbers.
If the council doesn't do this, you will see a down turn in specialist places being funded. Mark my words. The money has to come from somewhere.
