I was wondering more about the auto shutoff.
Oh, sorry. American cars are require to ship with a feature that shuts the engine off at stop lights, and restarts it when you take your foot off the brake. It’s done to supposedly help the environment, which it doesn’t do in the least and is also incredibly irritating.
So car hackers reconfigure their cars to disable that feature.
Can you show me the law that states auto start stop is a requirement?
It’s not explicitly required by law, but that doesn’t make it any less mandatory. It’s one of those “we’re not saying you have to, we’re just saying we’ll beat you up if you don't” rules federal agencies (EPA, in this case) love so much.
Car and Driver explains some of the reasoning here, though they forget to mention efficiency standards that are explicitly mandated.

Not all American cars have this. We literally just bought a Honda Civic and it doesn't have auto stop start. That's not to mention hybrids and electric cars. It's implemented by car manufacturers as far as I can tell in order to meet gas efficiency requirements of the NHTSA and it's mostly for larger consumer vehicles. SUV's, and trucks, not your average sedan. I don't think you represented this very well in your first comment.
According to the rental company I use for work travel, I’ve driven 33 different brand new cars this year, primarily sedans and small SUVs, all ICE (not a lot of EV on rental lots). Every single one had the auto start/stop feature.
Vehicles without it exist, especially as you mention full and partial electrics. But I’m perfectly comfortable with how I represented the situation based on my own experiences.
