Is there a valid reason, in terms of technology or wiring, for it taking, like a hundred years, for them to start manufacturing cars where the default is that your headlights turn off when you turn off your ignition?
answer:Volvo and Saab have had it for years. When I had my ‘82 Volvo, I left my lights on all the time, because they’d go off when i turned off the car. I think it’s not on American cars because of a lack of imagination.
