If this is correct then based on the stopping distances given in the highway code, whenever it is necessary to use dipped beam due to oncoming traffic in the distance it would only be safe to drive on a straight road at between 30 and 40mph.
I just wondered if other drivers on this forum do this too because in practice when doing 40mph or less on an unlit NSL road for a prolonged time due to multiple vehicles heading towards me I always feel like I am driving remarkably slowly and much slower than most drivers tend to do.

Something else and please don't see this as being critical but when did you last have your eyesight tested? It's worth asking whoever tests you to comment upon your potential night vision. Some, unfortunately, don't have very good night vision.
When I was an IAM Observer I always used to, carefully, ask this of Associates and always take them for at least one night session, so I could get a feel for their ability in that situation.
