I just realized (after looking at the turbine wheels for I don't know how many months) that they are non-directional: the ones on the left side of the car 'point forwards' and the ones on the right side 'point backwards'. In other words the left wheels present the blunt face of the blade to the front when driving forwards, whereas the right wheels present the angled face.
I'd always assumed the wheels were mirrored on either side of the car.
Shows how much attention I was paying.
Makes rotating tires easier.
