From "The Economist":

"Such devices are illegal to sell or use, but they have become popular
with commercial drivers who object to their employers tracking their
every move. A jammer prevents a tracking device in the vehicle from
determining (and then reporting) its location and speed—but it also
disrupts GPS signals for others nearby."

I still don't understand this -- are trucking companies so dense that
they can't figure out that one of their drivers is jamming the GPS
signal? Seems like a driver who jams the signal would soon be looking
for a new job.

Many of the trucking outfits use "contract"drivers who don't work
directly for them and have little control over what they do, for them
the GPS tracking is more of a "where is the load now" deal...
