So as an experiment, at 70 mph I put my face down on the gas tank: I could see the highway lines on either side, but literally nothing ahead. I wanted to see how long I could hold that position without freaking out. Answer: about twenty seconds.
This is far from the only experiment I did back then, I’m lucky to be alive.
For others left wondering what this meant, I think GP meant "I often drive with [the sun] in my eyes at dawn/dusk .."
This is still not 100% safe (especially in blind corners), but this is the minimum One should do.
And what? Be the lead car of the N-car pileup?
It's real easy to spit out idealized "never/always" type crap on the internet but meatspace is full of nuance and no rules of thumb can save you from having to make judgement calls.
I have driven on the motorway in heavy fog, and like everyone around me I slowed down, and there were no accidents.
Acting like an idiot because you think others will is not a good course of action, especially when you will cause issues to the majority who do not act like idiots.
Not sure how to say it, but try to never do that going forward, please, for your sake and for the sake of the others who share the same road with you. Yes, driving "blind" for one second, maybe two seconds (even though it's uncomfortable for me at this point) from time to time is not the end of the world, particularly if you're driving straight and you had "scanned" the road in front of you beforehand, but driving while "trusting" in others will get you into accidents. Never drive faster than you can see.
