I used that silly example as a means to demonstrate whatB can happen when
using extreme geometry that helps turning,B is used for accurate straight line
running.
If you nee a little wheel "feel" 2deg positive or negative caster with no
scrub might work (neg. might even help eliminate spins.)

Subject: Re: [Land-speed] Car Spins
Sprint cars are a good example Doug.
Apparently some sprinters actually have king pin caster only on the front
left to jack the right rear. The other king pin has little layback.
Excellent info from this discussion.
1. Run castor for it's desirable self centering effect.
2. Set up your front wheel offset to give zero scrub radius to lessen rear
wheel loading with steering input.
