I don't understand the reasoning you are making here. Cars have had advanced safety features like emergency breaking for a long time now (e.g. Toyota Crown Majesta 2003). Furthermore, there are many safety features that are controlled by software (e.g. airbags and seatbelts) that exist in all cars manufactured today.

Well.. just Google "unintentional airbag deployment."

Equipment that isn't controlled by software is also prone to failure. Unintentional airbag deployment is a very rare phenomenon.

Some of them were caused by nothing other than faulty software. Which is the point. The more links in the chain the higher the overall failure rate. Which has implications on MTBF but also on overall failed deployments.
