A driver ON the phone is far less dangerous than a driver looking at
the phone, pushing buttons, trying to work out why his call just
dropped out.

Maybe you could work out something (with frequency Doppler-shift? :-
P ), so it doesn't do anything unless the offending phone is moving
away from the jammer. That way you could be pretty sure the resulting
distracted driver doesn't run you over.
