What comes to my mind with the question of software for both Toyota and self-driving cars is both architecture/design and understanding safety/failure modes. Although the details are vague, it sounds like there were both architecture/design issues and safety issues.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
