The real concern should be remote-exploitation (e.g. via radio transmission). Someone will discover an exploit and publish it online.

The exploit will go un-addressed until government-owned vehicles start getting disabled. Then, governments will coerce manufacturers to turn disable the kill switch in all government cars. But that won't apply to person cars of government employees/officials, nor the cars that deliver stuff to government buildings.

Whoever wrote the kill switch provision was probably well-paid for their lack of foresight.

my car got stolen and the cops did absolutely nothing. I got it back because i had gps tracking on my phone. They only got involved when I told them where the car was after reporting it stolen. I would have thought they'd have an 800 number for sirius to call when a car was stolen.

Really hate how the state interferes with the market.
