It’s the same reason you can go in the garage, shut the door, and start the car on a 2026 vehicle. It will take quite a while before you die. No try that with a 1974 Oldsmobile. You’ll be dead in minutes. The cars today are clean. We need to stop chasing that fraction of a percent to make them cleaner. It’s having the opposite effect. Start stop, afm, dem, def, all diminishing returns leading to reliability issues. More pollution not less (where are all these used batteries going to go) with the mining of these minerals. LA also got cleaned up by industry regulations. Same with rivers and lakes. That was common sense stuff. Start stop on an automobile is just dumb.
