Listen to yourself here. Your solution is "be rich"

So what happens is you either create a cliff or you pull everything down too. Lemon markets for the poor or lemon markets for everyone. Neither is good

I never bought a used car, or any car at all. And I did that before I was rich.

In fact, poor people generally can't afford cars in the first place.

Huh, what? Reputation still works, even for poor customers. And so do warranties and insurances.

And you seem to imply that regulation can magically make the problem go away? It can't. Typically, regulation in this case raises the prices for everyone by demanding certain features, whether users want them or not. (But details depend on exactly what regulation you propose.)

I'm guessing you're not American. In the US, about 40% of homeless people live in cars. You can get a car for a song here.

I bought a car when I was poor. It was $2k. Why? Because if I didn't buy a car a 20 minute drive to work was a 2hr bus ride. You will, in fact, find that lots of people buy cheap cars. Go look at how many cars exist at used car lots or even your local Craigslist. You think those are just listings and no one is every buying?

  > Huh, what? Reputation still works

You misunderstand. Apple and Google have reputations but their products still have a lot of shit.

Never claimed this. Don't put words in my mouth. Which you seem to have this all figured out. I suggest you write a paper. Go win your Nobel prize. ¯\_(ツ)_/¯
