I've had that a good bit: I don't mind it too much, as long as visibility's good enough that it's obvious there's no-one coming the other way.
At least it proves they've seen you ...
It's not just (as I explained to my grandmother during an ovivacuation tutorial) the view of the stuff coming the other way, it's also the pavements on both sides that may contain pedestrians / pavement-cyclists / small children on scooters / etc., none of whom are expecting something driving at them in the wrong direction at an island crossing as they step / whiz out.
Agreed. I was being lazy (and inaccurate, and vehicle-centric) in using 'someone coming the other way' as a shorthand for 'anyone with whom this unexpected vehicle movement might come into conflict,' but IME car drivers tend to only wrong-side at traffic islands when there's no-one else about except the cyclist they're overtaking. Motorcyclists*, OTOH, will happily use it as a means of overtaking an traffic queue ... complete with busy pavements on both sides and poor visibility through the queuing vehicles ...
But a nice solid traffic island between you and the closest approach of an idiot is definitely a result.
Aye, no doubt about that.
* OK, OK, some motorcyclists. And moped riders. And scooterists.
