The Spitfire might well have the tightest turning radius when moving as slowly 
as an infant crawls.  But put it up to a 
walking pace, the and front wheels scrub horribly.  A fwd car, like my old CRX, 
which had a wider turning radius of 
30', would keep that tight turning radius at a walking pace, even a jogging 
pace.  Hence, it would turn quite a bit 
tighter then a Spitfire will in a parking lot, or even trying to turn around in 
my driveway.
