The PickCanvas methods do not always return an intersection when picking on
either of the two sides in my example, and never return an intersection when
picking the roof, windows, hood, trunk etc. I think this is a bug in one of
the picking utility classes that crops up when using Shape3Ds with multiple
geometries, and will file a bug report. My example is attached. I'd
appreciate any tips if I've done something wrong.

When I try to use PickResult.GetGeometryArrayIndex(), I get an exception
"GeometryArray: no capability to get vertex count". I'm having trouble
finding where to set that capability.

This is stored as part of the PickIntersection, since it is specific to the
intersection. Use PickIntersection.getGeometryArrayIndex().
PickIntersection.getGeometryArray() will return the array directly.
