One gizmo I dreamed up (but have not implemented) is to build a device
which resembles a windspeed guage, but with cube-corner reflectors
instead of cups. If this is placed in the radar beam while rotating in the
correct direction (even the vehicles wind of passage could do this), from
the
front it would register a strong reflection which is moving much slower
than the device as a whole.
For plausible deniability, you could hook it up to a meter and *call* *it*
a wind guage.
Similarly, appropriately sculpted hubcaps could mess with the radar
guns tiny mind.
Note that these devices are 100% passive, which would avoid FCC
problems (though not neccesarily LEA ones).
