MPs are stupid then. Which thankfully this article points out. Apple (and I assume Android) already allow for remote bricking/locking of your devices. Apple won't let you disable Find My or other security measures without your passcode and Apple has a way to disable turning off Find My if you aren't home/normal location (so if someone snatches your phone while you are out and they also shoulder-surfed your passcode they still can't disable it).
I have no clue what "strong commercial incentives" these MPs are referring to but I assume it's just general (tech or otherwise) incompetency of elected officials.
Here they hook into the CAN bus directly from the outside.
