I've done rural night driving in my Tesla Model 3. Yes, the display can be dimmed down well below the headlight reflection luminosity. The display also switches into night-mode automatically at sunset, where the colors become grey-on-black instead of black-on-white.
You're right about the red theme, it would be welcome.
If you really must have an OLED then you might have to wait until Tesla or someone releases a car with an OLED. But this issue of being blinded by the screen has not at all been a problem for my use of my Model 3. Also I am quite sensitive to darkness, so I ought to know... I am a pilot, and I am very aware of the need to keep your night vision sharp. The Tesla Model 3 controls have worked for me. They're not perfect, but I've rarely had the screen blast to life and shred my night vision. Maybe one time, but that was only when getting in the car while it sat unused through sunset, and it fixed itself in under a half second. The cabin controls allow me to totally black out the interior of I want, and the minimum brightness adjustments are well tuned so that at night the very bottom end of the adjustment range is actually effective.
So this might really not be as much of an issue as you suspect. But there's only really one way to find out, and that's go try one out.
We all have different sensitivities here. All our eyes are different. Mayhap, I'm more sensitive to dim light, more distracted, etc. Whatever the case... I've modified many cars I've bought, to allow me to completely turn off all internal back-lighting on all controls.
I don't want a light glow on my traditional speedometer. My radio analog controls, door lock button, and other controls to have ANY lighting. It's annoying, distracting, and I don't want it.
So considering this, imagine how annoying I find a massive LCD with any backlight. Even the dimmest backlight is many times brighter than a turned down analog backlight on classic style car displays, buttons, knobs, etc.
My beef here is threefold.
1) Why on Earth is my speedometer to the right, so I have to turn my head to see it. Why is the speedometer not always there?
2) Why is it on a display that always has glowing light, or I can't see it. NOTE: yes, I can see a traditional car speedometer with only starlight/moonlight. No, I'm not mistaken, yes I can.. so says 32 years of driving.
3) Oh, I wanted to try a Tesla. But where?
Where would I do that? Even when they had dealerships, which they've closed most of, there aren't many in my region.
There's a whole ball of 'Tesla is still in its silly stage', such as not having anyone within 500km who can fix my car, not being able to buy parts, local dealers not being able to fix them, and the absurdity of thinking roving repair shops can fix a car at -40C, in the middle of an ice-bound street, during snow storms...
But beyond that, I actually was in California and thought "Why not make their job easy, I'll test drive one here!"
Nope. Sorry. Was flatly told no, as I didn't have California drivers license. I explained several times that I was on vacation, but the mantra was that "I can't buy local, so I can't test drive local."
Of course, this isn't germane, but you did poke the whole "just try it" into my face.. so I had to respond. ;P
