Line Up and Wait
The discussion has been about similar instructions where ATC has no responsibility for separation. The disagreement has been whether or not the pilot must adhere to invalid ATC instructions.
I agree that ATC is not responsible for separating VFR aircraft in class E.
I sort of agree that a pilot need not adhere to an invalid ATC instruction.
I disagree that an ATC instruction to a VFR aircraft in Class E = an invalid instruction.
ATC may not have the responsibility to issues instructions of VFR aircraft in Class E, but that does not mean that ATC does not have the authority to issue instructions to VFR aircraft in Class E.
