Cyber Security of the Connected Car in the Age of the Internet of Things by David Moss via @datafloq

As innovative and fun as these connected cars are to drive, they are not without flaws (mainly caused by poorly written software), which could compromise drivers' physical and personal safety. Automobile industry insiders are becoming increasingly aware of the security risks found with owning and driving a connected car today. The risks that come with a connected car being hacked can be enormous, hence the importance of cyber security

I can think of nothing worse than having your car hacked and something changing to cause an accident.  It feels like a sci-fi plot but could become reality.
