Any vehicle with 4 non-steering wheels will pay the penalty of friction in a turn. Friction that increases exponentially as the radius shortens. You learn quite quickly to plan for shallow, gentle turns, and you can always assist with a bit of a shove where needed.
On the other hand having 4 wheels means you can fit 4 motors, which means an Exclusive has the same weight/motor ratio as a very light sub-1000kg caravan. Which is a huge advantage and far outweighs the downside, being the cost of 2 extra motors, larger batteries and 4 motors to engage/disengage from the wheels.
