With the stories in recent months about Valasek and Miller hacking into a Jeep (http://www.wired.com/2015/07/hackers-remotely-kill-jeep-highway), and the fact that they did this on a Ford Escape and Toyoda Prius in 2013, vehicle hacking is now a real and impending threat. Research into how this is done from a technical perspective, and give your thoughts on what automakers or the manufacturers of their parts/software/firmware can do in an attempt to mitigate this threat. What would happen if Google's self-driving car (http://www.google.com/selfdrivingcar) was compromised? Do you think Google or other companies working on these self-driving cars can release them for use to the public with the possibility of a hacker somehow taking over?
