If the US government gets its way, it will require car manufacturers to install kill switches in all new vehicles (cars, trucks, and SUVs) from 2026. The kill switch will have a backdoor that can be accessed by law enforcement.
See the text of the bill here.
But, as House Representative Bob Barr noted in an article last year, legislation can change unexpectedly to work against law-abiding citizens.
The kill switch will not only remotely shut down a vehicle but the technology will also “passively monitor the performance of a motor vehicle to accurately identify whether that driver may be impaired.”
