Old cars could actually have their stuff adjusted, though. You’d have to tinker with the carburator if the weather was significantly colder/hotter, etc. to get it to run properly.
Even cars in the 90s started getting too complex - electronic fuel injection, variable valve timing, and more. There’s no need to adjust the valves because the computer does it, and better than you could.
I doubt it matters what we think anymore. It barely did before, but I can’t see any light at the end of this American Experiment tunnel.
