Thanks for the link.
I still think this is ivory-tower stuff. I'd give the bad guys 2 months to figure out how to arrange for a "plan b" in event of being tagged - they get a half mile ahead of LEO's pursuing them and call a buddy on their cell phone.
Buddy has a waiting doberman wearing a fat collar. Bad guy pulls up at arranged meeting place for 15 seconds, while his buddy pulls the tracker off the back bumper - and sticks it onto the doberman - and lets it go.
Officers spend the next three hours, chasing the dog around South Central, Fox 11 filming the whole time.
Good for Fox ratings. Great entertainment. Probably spawn a whole series of new movie plots.
I just don't think this is realistic. You need to STOP the car. Bad guys have brains too. They'll figure out how to defeat the tracking thing in no time.
It's a waste of money. Make it stop the car. Then spend the money on it.
Maybe Metal Storm can sneak in a few of their High Explosive 40mm grenades in the tube.
