When I see the slightest hint of an exit, overtaking and offsiding are no longer part of the plan. It seems to me that the Google car offsided unnecessarily and across a drive exit/entrance (the one with the loose surface just around the bend).
I think that if I had offsided where the Google car did, that I would probably have pulled over before the drive. I need to check that on the map view of the bend but I probably wouldn't have offsided that bend anyway as it's not that sharp, there is plenty of view even with mid summer foliage and I couldn't see any advantage from doing so.
I was looking at some links posted here about the Westbound Shoreham bypass tunnel approach, regarding accidents that occur just before the tunnel and found a few shots of a rear seat passenger in a passing black car, making gestures at the Google camera. Perhaps the Google car driver who offsided, was expecting to find the same people throwing moonies at him from somewhere beyond the unextended limit point? It must get wearing having folk doing stuff like that while you're sauntering around the NSLs, while at 'work'.
A wise man once told me that "it depends". I sometimes agree.
