+1a. Security Myths:
+
+Anyone can see open source code, so it's easier to create security exploits.

+Hiding code does not make a product safer.
+
+
+1a. Maintainability
+
+Car manufacturers get most of their software stack from third-party vendors who
+put all the security liability on the manufacturers. There is no incentive to
+update or keep their software secure. Since, car manufacturers have such a long
+ramp-up time for safety approval and they have to maintain the car software
+stack for 7-10 years, they are turning to open source.

+
+"What's not so obvious is that as complexity grows, the ability to innovate
+shrinks. Why? Because if more and more of your development time and resources
+are spent managing development options, associated requirements, and integration
+testing, less time, money, expertise, and creative energy are available for
+invention."

+"Open source maintainership is for life."
