As a German, saying that is lunacy given the sheer amount of jobs connected to them - but I really hope the big traditional car makers get their comeuppance for being utterly shitty greedy fucks.
Dieselgate really gets me down whenever I think about this stuff, since it's the most blatant and obvious fuckery in the face of willful, direct, large-scale, endangerment of human life. (Not even considering that they were fucking with our planet on an even grander scale, that's just the cherry on top.) This is as cut-and-dry and high-profile as a case can be, really.
And yet... a buncha fancy-sounding fines that bothered them none, a couple of well-paid peeps had to go earn their money elsewhere, there was some public outrage for a few weeks - and after the news cycle had switched over to whatever was next, no one cared anymore. The cars didn't magically become less designed to spew out noxious fumes, still continue to kill people every day in cities around the world. It's not like they went poof once the fines were handed out, and the fixes the industry proposed are mostly just cost-effective PR stunts. This is a direct threat to thousands, and it was designed that way.
If I meticulously planned out and then at great cost implemented a plan to viciously choke-murder a couple of people every day worldwide, I'd get locked away in the slammer for the rest of my life and probably get shanked by my inmates for being a vile monster. Purposefully breaking the rules on that scale, with demonstrable immediate effects and at-best-unknown-but-certainly-not-good long term consequences should be an existential threat to companies, not this kinda hand slappy business.

And yes, worldwide connected industries, global economic downturn, livelihood of millions affected, yadda yadda. Am aware. Still annoyed as fuck my leftie "fat government" fantasy didn't play out.
I still believe we need a bat signal of sorts. Some sort of global catastrophe that shakes peeps deeply enough to actually make them press for change, and inconvenient enough to keep that pressure going for a while. I had hoped this one would've been it, but eh.
