These phones would each include a sophisticated microprocessor and be "always on" and "always talking and sending" to and from the main station.
The main station would be connected to all parts of the country via a hardened network of cell phone towers. Monitoring of each car would be 24/7. Hence, doctoring of the automatic minder would be extremely difficult.
There would be numerous internal sensors to detect tampering. Tampering would be communicated instantly to the main station.
Take down of a cell phone tower would have to be rare. There would need to be some tower redundancy in any case. When a tower went down, any car thereby cut off from contact would immediately be quarantined and grounded. A traveling repair company would recertify each vehicle's minder before it was allowed to move.
All moving cars would have their automatic minder monitored by a combination of UAVs, roadblock monitoring stations, and troops with cell phone-enabled laptops. (Alternately, Wi-Fi or some other technology might be used in place of cell phone. Probably a different, military type of communications net with more security than cell phones or Wi-Fi.)
The automatic minder would be connected to tamper-resistant sensors inside the car as well as possessed of remote monitoring capablities (near remote--as inside the car but outside the automatic minder.) The placement of explosives into the car would probably be detected.
In addition, the automatic minder would include a profile of the owner and all registered drivers for the vehicle. Anyone caught driving a vehicle who was not a registered driver for that vehicle would be arrested. All monitoring stations could query the automatic minder for this info, or query the main database using the car ID #.
The continuous reports of the automatic minder would provide a record to the main database of all travel of all cars, so suspicious travel (ie, trips to the Syrian border) could be investigated.

Great - another reason for Bush to ask for a few more hundred billion dollars to waste on the Iraqi people, who still refuse to take advantage of the gift that 1600+ dead Americans gave them.
Sorry, I'll pass. We can't even get electricity and running water going for more than 8 hours or so. Your suggestion, although admirable, would be impossible to implement.
The terrorists are now treating the Iraqis like the Israelis.
It's about time that was pointed out to them. Might change a few minds . . . or get one's throat slit for making the comparison.

How many of these bombers are unwilling dupes? The remote technologies you refer to make this very possible.
