It's the "it took 10-20 years" thing. Really, the advance of digital technology made it all work out in the end - trying to do all that stuff in the mechanical domain was charming but it took more talent than was readily available and raised the price of cars. Digital just means a different class of engineer could address the problem and the replicability of digital helped. A generation had to exit the workforce and be replaced for it to actually work. My more central point is that they didn't have to be polluting at all, using older technology. Properly tuned engines didn't pollute much. Most if not all issues addressed were really down to proper maintenance. The "people who aren't there" in the modern software that runs cars do that for you now. As hard as it may be to believe, people were more or less expected to do their own maintenance on cars. Of course they didn't. But that is just how I was raised. Again, we use cars to rejigger location in real estate. It's the use of a technology to solve something that is ultimately a governance problem. I suspect land rent taxes would be more efficient.
