> They don't want engineers testing code out on real people's lives.
When Tesla pushes and runs code in the shadow mode, it is run in parallel to the "production" version of the software. The actual behavior of a car, even with the test code in, still relies on decisions made by the "production" version of the software[1]. The purpose of such testing is to compare decisions made by the updated code vs those made by the old version, and use this info for fine-tuning the next gen algorithms.

I would like more info on what it takes to establish battery production for the output of millions of cars (especially in terms of resource availability and timescale for the big players). Pretty much all the articles I saw skip this point all together.
