I'll do you one better, car headlights should never be off while the motor is running. Just like motorcycles since the 70s (maybe 80s?).
No switch at all, ignition on, headlights on, period.
Niche counter example:
Parents who sit in their idling cars for (fucking) ages while their cars are facing the tennis courts thus blinding the player on the other side of the court for however long it takes them to either turn their car off, drive off, or someone to tell them turn their fucking headlights off.
Along similar lines would be those people who constantly start up their cars in campgrounds after hours for whatever reason.
How long have you been holding that one?
It's only been a recent thing, noticeably more frequent the last couple of years.
Before that I've not had to intervene at all, as far as I can remember.
There aren't that many courts where cars park facing them, but my home courts are one of them ;)
Simple solution: when the wheels start rolling, the lights come on.
I'd still prefer to override both on/off though.
Personally I feel like cars with headlights in the daytime on days with good visibility can be too noticeable. I find myself giving them too much attention because they stand out more in my visual field.
When the oncoming cars do not have headlights on I find it easier to give them just enough attention to see that they are behaving normally leaving more attention to devote to things other than oncoming cars.
I like this. Turns out a few countries require DRL: https://en.wikipedia.org/wiki/Daytime_running_lamp
But what about for electric cars? Maybe whenever the car is in anything other than P, and for 5 minutes after P?
