Probably just different from what you're used to - it's electrically power assisted, rather than hydraulic IIRC - perhaps that's the difference?
Steering is one thing that the car is often criticised for - it's not as sharp as a Boxster's for instance.

OK, those roundabouts have very slippery tarmac bits which are a lot of fun - I live in that area near the Rashid Hospital R/A and if you know the Gulf Towers R/A that is a great place to slide 
and to be careful when you are entering - maybe it was that, though not to sure. Maybe you are just used to sharper steering from Elises etc.?

I'm near the American hospital and Wafi and that roundabout is exactly the same.
I've just had to pop out
and there was nothing like it so it must have been the surface.
Just realised we are talking about the same roundabout haha.

For the time being until I get the rear tyre issue sorted, I'm happy for the front to be a little softer.
Also, when I got back I was able to park my car within view of my office window.
Excellent

Are you sure this isn't just the passive rear wheel steering?
The rear wheels alter their toe in if you accellerate slightly while turning, sounds like you're just experienceing that to me.
Go into the roundabout on a trailing throttle, the front end seems to push wide a little, take up the throttle and the car almost seems to 'steer' from the back, tightening the line at the front? That's the rear wheel steering.

It was at very slow speeds, barely moving.
The only other thing I can think of is that we sometimes get very shiney bits of tarmac on roundabouts that allow you to slide and you don't even know it.
It was the roundabout just before Maktoum Bridge near Oud Metha.

You will get tyre scrub in those situations in most Japanese cars, because they don't use Ackermann steering geometry.
The steering arms are not angled to point at the centreline of the rear axle, so that the inner wheel turns in further than the outer wheel, countering scrub (Ackermann principle)
They are instead parallel (for consistent high speed behavious and to reduce bumpsteer). This creates the scrub in tight turns.

Thanks for that Nick. It wasn't that tight so I do think it was the road. Some of the roundabouts here are like glass (mucho fun ).
I popped out earlier and did a U-turn and it was fine then so it must be that.
