Agreed, this is a viable response.

And if you get so hungry at the time because of this association,
remember to test the microwave oven for leakage, and keep any leakage
below the point of human danger.  You may have to create some leakage
to test the test instrument.

I guess, the microwave oven option won't work as reliably if the
vehicle is using 5.8 GHz, but that would be something to test.  5.8
GHz has a shorter range though.

Bird netting is quite cheap.  Do you have a bird problem?  ;-)
