The man wants MORE caster. How about this idea?

I just love the way Blu does that, I open a door, he bursts right in and fills the void with his tech and minutiae, then leaves supporting my point.
Big caster causes heavy steering in traffic and parking lots, which may be challenging for small folks who aren't expecting it .

You don't need a ton of caster to get directional stabilty .
Thnx Blu
