Lets wait and see the test results. I forsee buildings and pedestrians being hit with stray darts.
Give one to the Texas Border Patrol;)
At least they'll know where they are.
I think that soon new technology will combine the vehicles operating computer and a chip in the license plate to coordinate and complete the needed information for a satellite to shut down the vehicle's power to a low speed for stopping.
Then all the LEO would have to do is type the plate number into a satellite computer up link and it would shut them down. Even if this is not in the future an on board GPS locater would be simple to accomplish without the necessity of shooting at the vehicle with a locater attachment.
Why not? they already use the computer data to tell the last few minutes of operation before a crash. And if they can unlock your doors they already know where you are.......
