I'm thinking along similar lines, for bikes.
Whether lsr bike-- or car-- "rake" doesn't seem to matter a whole lot. But
lots of "trail" should help stability, in any case. Typically, trail is
increased by increasing rake-- which eventually unloads the front contact
patch too much. A trailing linkage avoids this problem. As you say-- like
a shopping cart wheel.
(BTW, I'm not talking about rws here, so don't anybody start thinking I want
to build a rws bike. Furthest thing from my mind. I won't even drive a
forklift very fast.)

Jack, exactly. But rake and trail are the same as large amounts of caster.
Think of the bike's steering head as the kingpin . It intersects the surface
way ahead of the contact patch on the tire. I was thinking more the shopping
cart front wheels with a vertical shatf but the contact patch trailing.
