It sounds like Tesla is more focused on Iron based chemistries compared to what we heard at Battery Day.
Has that been driven by production challenges scaling high nickel cells, constraints on supply chain / raw materials, or something else?

There are vast amounts of iron (and lithium) on Earth, but much less nickel.
For global industry to scale battery production to ~10 TWh/year, it needs to be mostly iron.
Higher energy density of Nickel only needed for very long range vehicles & aircraft.
