CAN bus for everything maybe not such a good idea?

Thieves Can Steal Modern Cars By Tapping Into a Headlight Wire

CAN Injection: keyless car theft | Dr. Ken Tindell



Using CAN bus for everything is now leading to CAN injection attacks where thieves can get into a car just by jacking into a headlight plug, or more recently with bluetooth speakers that inject data into the CAN bus.

Not to be a luddite, but I've always thought that CAN should end at a relay and the cables going to the actual extremities of a car should be "dumb". And I've never liked the forced integration of car features with the infotainment. IMO have a dedicated function screen and give me a standard 2DIN.
