Most technology is so cheap to manufacture that it pays to include it in all production and simply give it an "off switch" that can be used to block its use. Those who want, and can afford, the extra features get them unblocked from the factories or dealerships.

This will be a tremendous benefit to hackers. Any technology that can be programmed can be hacked and the off switch turned to the on position. Look for the proliferation of YouTube videos showing us how to do just that and thwarting the unearned profits.
