Someone would actually WANT a smaller wheel?  That huge thing was the
first thing that struck me when I test-drove my van at the dealer.  Told
my husband it felt like I was driving a bus at first (like real
big-bus).  It was very different being so big, but also EXTREMELY
comfortable.  I don't know, maybe it's just me, but it's a perfect fit.
My elbows can rest comfortably on the armrests and hold each side of the
wheel.  Very stress-free driving.  My husband thinks so too - can
easily, comfortably, drive long trips.

I just can't see a smaller wheel being comfortable, but that's just me I
guess.

Just my two cents,
Tonya
