"Probably a deeply unfashionable thing to say, but I love driving, and being able to glimpse stonehenge from the road ...."
Not unfashionable at all. It's one of the Great Views and it would be entirely lost.
"Does anybody have access to a report on the direct disturbance or damage to scheduled monuments in the area?"
Proximity to Blick Mead and disruption of the Winter solstice spectacle are 2 issues but of course if you dig anywhere there you wreck something and what that will be is yet to be known..
