Dan sounds like he's writing for someone who grew up with The Car (TM) and is now disillusioned by all the bollocks that came before. For most of the people he's talking about a car will be a non-entity. Mr. Regular wrote that Road and Track post about the lecturer who hates cars, and that honestly sounds (to me) like the person who is really going to respond to what he's describing. Everyone else who can't afford that dream probably isn't thinking about it. I've been putting off my driving licence for years because I know I won't be able to afford a car. But as a product that designed and manufactured, the car holds interest because of how the end user is envisioned, how the company has engineered a solution for a given problem, how the company's self-image has impacted the final product, the weird ways politics can find its way into any given product. Just because cars (and driving) are pain in the arse, does not mean there aren't millenials getting something else from cars (rolling hi-fi for parties).
Having gone through all that nausea, I will say that a strong, small-scale story arc will probably save all kinds of sins in the making of it.
Stainless steel contains chromium/chrome within the steel to oxidise in preference to the Iron and form the sort of protective oxide coating that iron doesn't. It also has a reputation to be brittle compared to a similarly stiff non-stainless grade of steel.
Galvanised steel has something attached to the steel to oxidise in preference to the steel, usually some kind of Zinc coating. If you've ever heard of people replacing 'Zinc Anodes' for big steel structures, those steel structures are galvanised. The term 'galvanised' is reference to the chemistry of rusting.
