intresting read i can think of a few problems that might or might not happen. cars already use special hardenend insert steel components in todays cars proofing a problem to correct repair by penal beaters.

Sounds pretty good overall, but a massive problem for future panelbeaters. It's going to be interesting to see how those panels can be repaired (Even for minor dents) & as for painting . > >>>

I notice the "source" of the article is the producer of the new wonder material.

In construction the grade 500 reinforcing steel bars for concrete are made of the same stuff as the grade 300 bars, and the extra strength comes via a heat treatment. Which is fine, but you can only bend the bars once, if a bend accidentally gets bent back, then that's the end of it.
You are also quite restricted in what welding procedures you can use on it - meaning that if someone accidentally cuts through your main structural reinforcing bars with a concrete saw, the fixup is usually fairly expensive.
If you build a car out of wonder steel that relies on heat treatment for a lot of its performance, I wonder how repairers will get on with bending bent things back to shape, or cutting out rotten bits and welding new steel in?
(Or does that not matter in today's brave new world, where building cars that depreciate to scrap value in 15 years or less is considered somehow "good for the environment". ? )

car penals be All glued togather no welding possible i would say on wonder thin armor proof tin can-cars.

It reads like it's more ductile - one of the claimed cost advantages is it's able to be cold-pressed to make structural components of similar strength and weight to more expensive steels which need to be hot pressed. or as it's stronger, then used for lighter weight replacement of components and panels etc which are already cold-pressed. It might actually be easier / better for repair than conventional steels.
