If you don't mind me asking, does your son have a sense of danger?
Our son doesn't have it; he will just run on the street if we don't always hold his hand. His walking is very clumsy. We are hoping to get HRM just because we could have access to the Motability scheme; otherwise, we cannot afford a car.
We would rather not have to care but have Motability because of that, as we struggle in that part when we go to school, etc.
