West Coast Drive is Illegal?

[piersklein]

Please read the blue box of the rule:

To determine the FRAME PERIMETER, wrap a piece of string around the ROBOT at the BUMPER ZONE described in R22. The string describes this polygon.

The frame perimeter is composed by non articulating structural elements but is defined by wrapping a string around the robot at the bumper zone. As such, a west coast drive that is under the max frame perimeter while determined by this method would be legal.
