The moose didn't appear during the testing, it's a basic obstacle avoidance test.
It got its name from the moose as that's what they do: stand on the road at night ignorant of approaching traffic - or in tunnels, which is wildly scary ! - forcing drivers to swerve around them.

I also think the difference in track derives from this incident as well.

IIRC, that was indeed the case.
The prototype or pre-production Smart in the Brussels Autoworld has less flare on the rear fender than the later production versions, and what
look like same-sized tyres front and rear..

I think the vehicle darting around is an indication of this instability.

My thoughts exactly.
Pushed hard(er) it'll lose the rear end.
