I can’t offer any comparison between the Us and the UK, but I have some experience of having a neurodivergent child in the UK. We live in the NE of England, an area which is on average pretty deprived by UK standards*, however the support from the primary and secondary state schools we have used has been exceptional, with additional staffing as required and sensitive adaptions to needs throughout. There was some bullying at one point in primary school, but that was dealt with promptly and effectively and strategies were put in place to avoid social isolation - things it would never have occurred to me to do. The support for LGBTQ kids in secondary has also been pleasantly surprising - to the point that those who try to pick on trans kids find themselves becoming persona non grata pretty quickly.
There are some pretty huge cultural differences between the UK and the US, as you will know, and I suspect adjusting to those are going to be the primary problem in the move, rather than the support for a neurodivergent or SEN child.
*I feel like I should stand up for my adopted North-East; whilst it’s true that there are deprived areas, the NE is a beautiful place, the people are friendly and welcoming and the cost of living is low compared to many areas. The accents are proper canny too!
It was the Honda FRV and I still have one. I also had a Multipla. Both are good, in their own quirky ways. Both have slightly narrower seats than a normal car; the honda slightly narrower, but more supportive, have heating and are leather. Both are very car-like to drive, but the Honda has way better engines and better reliability. That said, getting parts for the FRV is a pain, because there weren’t many made and the wider body means that a surprising number aren’t shared with other Honda models if the same era.
Given a choice, as a practical family car, I’d take the FRV over the multipla. I do have a soft spot for the multiplugly though.
