I have a few specific thoughts but no definitive answer.
First and given the opportunity, I would off-side to some degree, increasing the lateral separation between myself and potential danger.
Second is that I should try to approach the junction carrying no more speed than a driver coming to a stop on that side road might reasonably expect. From what I've seen, most drivers expect cars to be approaching at no more than about 50 mph in an NSL, so that might be my guide, modified by the degree of lateral separation I've managed to gain in the first step.
My last thought is that an emergency stop is exactly that, so I should be aware of stopping distances at various speeds, and that should also guide my approach. It doesn't have to be tidy as long as it's effective.
Thinking more generally now, many junctions have some visibility across their entrance, and that can give a driver enough confidence to approach at a higher speed than would otherwise be the case.
It's urban situations where the scenario outlined by
TripleS is more readily apparaent, as there are many drive-ways and footpaths hidden by the corners of buildings, in exactly the same way that small children and dogs can be hidden by parked cars or vans.
It is for this reason that I think that most drivers, advanced or otherwise, drive too quickly through built-up areas. I should be clear about this - I don't expect drivers to crawl through urban areas, but instead to vary their speed according to hazard density, paying careful attention to lateral separation from those potential hazards.
