Sounds about right to me. I think it's worth mentioning you were not moving (and handbrake on perhaps), the neighbours are independant in that they were not in the car, involved in the accident, or close relatives etc. If the other driver's speed was a factor, mention it. E.g if other cars had safely passed you first, perhsps the reason he didn't was your speed, if you'd not moved, of course.
Good luck with it.
Btw, remember, insurance companies' first responsibilty is to their shareholders, not you.
