The more sophisticated jammers only switch on when a signal is detected,
hopefully quickly enough to stop a detonation.

They'll make electronic garage door openers, radio type car alarm tags and
a huge assortment of other things entertaining to use...

You'll just have to wait for the HMMWVs to drive past before your car
will unlock, your garage door open or your cordless phone ring.

It's counterproductive to shut down a neighbourhood, you just need to
prevent detonations within lethal distance.
