On a Tadpole there is a limit to the angle a given wheel can turn.
Made up of:-
a) diameter of wheel
b) distance wheel can turn before it hit's something
c) steering control components
I think it's fair to say that a and c are primarily factors of b. Assuming good steering layout C then A only comes into play when you've minimised B and then can only go further by reducing A

Taking it to silly lengths just to emphasise the point. Here the very wide swb turns around the centre of the rear wheel. It won't in reality because you could never get Ackerman's that far but just for theory lets assume it would. No part of the trike moves forward during the turn.

I think it's worth pointing out that turning circle alone isn't the be all and end all in negotiating a hazard which is the key point I think you are looking at Paul? I'm sorry but my cad skills are insufficient to model a long thin one vs a short fat one in negotiating a pedestrian island. Perhaps a job for some lego?
