I do think Motability have an agenda to push EV’s for much the same reasons the government do but I suspect it has less of an impact on AP’s than the OP thinks.
AP’s are dictated by the 3-5 year life cycle cost of the vehicle less the residual value, the favourable AP’s we are seeing right now have more to do with manufacturers heavily discounting EV’s due to falling sales than Motability trying to promote them.
Personally I would love to have an EV as it would suit my use case almost perfectly but I have no way to charge at home so it becomes practically and financially unviable unless public charging becomes more accessible and affordable.
If I seem a little strange, that's because I am.
