This kind of makes me want to go out and buy an old old car:
https://www.theregister.co.uk/2018/0...security_bugs/The researchers noted that their probing found flaws that could be exploited by an attacker to inject messages into a target vehicle's CAN bus the spinal cord, if you will, of the machine and engine control unit while the car was being driven. That would potentially allow miscreants to take over or interfere with the operation of the vehicle to at least some degree.
The idea someone else can hack my car on the road is about as scary as it can get.
