2021 LEXUS RX Back Over Prevention Warnings Problems

I want to bring 2 issues to your attention: First, with all the technology in vehicles today, I can't figure out why there isn't an audible warning if the lights aren't on at night and why they don't come on automatically when windshield wipers are turned on. I often find that I am driving without lights because either my wife or some valet turned them off from 'auto' without my knowledge. I have to imagine accidents have occurred because of this and it seems like such a simple problem to fix. Supposedly there is a law (though I've never seen it) in Florida that you have to have your lights on when it's raining. So why not just have them cone on with the wipers? Second, I am from Detroit so am familiar with cars. Or at least used to be. I recall some time ago that there were regulations...
