I like the "What were they thinking" patent series...
I agree, why limit the scope with the 'without a high-speed chase' wording. Plus, the technology mentioned doesn't necessarily prevent the high-speed chase. Maybe the thief begins high-speed when he sees the cop trying to "read" the bar code...
The 1st of the 3 'stopping means' is reasonable. However, the last two make no sense - endangering the public as the blowouts cause the thief to wreck into people/property...
The concept is interesting. However, I am certain that thieves would quickly determine ways around this technology. Like spray painting over the bar code, removing the On-Star (or equivalent remote technology) fuse(s), removing the On-Star (or equivalent remote technology) antenna, etc.
Back to the drawing board...
The best way to bring the car to a stop - actually to a slower speed - [once the best technology is determined] would be to send the ECM/PCM into Limp-Home-Mode. Then, the cops could easily stop the thief in a safe manner.
I'd say skip the bullets and go with explosive bolts to separate the drive train from the body.
I suspect that in the not too distant future, the police car will simply determine if the vehicle is exceeding the speed limit by a specified margin and if so, wirelessly instruct the vehicle to safely come to a stop. There will be plenty of civil liberty and privacy concerns, as well as hacking risk discussions, but eventually, I'm guessing this will be it.
Today, radar guns have to be calibrated at specific intervals or the results are not legally binding. You could create some soft of watchdog system, essentially equivalent to the the radar calibration, to minimize abuse.
There are so many holes in the patent, that I am sure the person just wanted to be able to say he had a patent, and that the entire things has no useful purpose. One of the test for a patent is that it must be "non obvious" and it certainly passes that test!
How to stop a car:
Hollywood style:Use the bazooka
Nerd's style:Engage the autopilot
Nutty professor style:Shoot supersticky glue on the tires
Norwegian style:Take actions to prevent there never will be as a reason for a chase
Scifi style:Cars? You mean those old ones on wheels?
Max style (Ill better take cover):Tell the driver that old card didn't go this fast ;p
(Ok, I could go on, but gotta get work done)
