“Anyone with a working knowledge of cars could disable them.”
What if it is software based?
Not sure how this would work for its intended purpose. Bluetooth? Need to be close for it to work. Cell connections? Must get plate number to get vin to disable.
The weak link is the communications. Cut the antenna. The cell connection is not really needed with phones hosting the apps.
Lots of older cars no longer connect with 3G going way. Same will probably happen with 4G and so on. So even once the feature comes out, it will most likely not work on cars older than 10 years.
