I always wonder about this as well. But of course, I wouldn't take it near the 0 miles left mark. When the fuel light comes on, I better think if I'm gonna make it to my destination and even if I do, will there be any gas station near by. When I'm under 20miles, I better find a gas station. Under 10, panic sets in. Lol

Direct Injection
I have a 17 RX and was under the impression that the new 6 had direct fuel injection which is more like a diesel injection system.. I think that engine also has a means to lessen the build up on the back of the intake valves that direct injection is known to cause. My humble opinion is to avoid running out of fuel !

In my experience Toyota leaves 2.5 gallons as reserve when the low fuel light comes on (which is when it says zero miles to go). So your average mpg X 2 to be safe.
In my RCF I could go approx 40 miles, wife’s Camry Hybrid can go 80ish. My 4Runner about 30.
If we fill any of them within a mile or so of the light the pump clicks off approx 2.5 gallons shy of the stated tank size in the manual. I.e the RCF says 17.4 gallons and mine rarely took more than 15 at a fill.

Keep in mind that in some cases fuel in the tank is used to cool off fuel pump. Running low on fuel can damage fuel pump diaphragm.
Long time ago I had a transportation business and on some of my cars I had to replace fuel pump every 6 months or so. It took some time to realize that some of the drivers were constantly driving with low fuel warning. And of course car manufacturers will never admit to it.
So that extra fuel left in the tank might not be there for "careless drivers" that like to ignore warnings, it might have another purpose.

typically I fill every Sunday, regardless of the level, I don't have time during the week to deviate from my commute path to get gas, Sundays are my only day off so I've made it a habit to refuel them then. But I know when the light come on there is about 2.5 gallons left in the tank..
but as I stated above, simple math shows how far you can go for the most part if the need ever comes up, 2 gallons x avg mpg gives you a good idea without having to actually run the tank dry to find out..

My range says 15-20 when the light comes on. I have gone 40 miles more after that. I have also put an additional 3 gallons of gas in after it clicked off but I don’t recommend that.

I think this is all a vicious cycle - consumers think "Empty doesn't mean empty, I can go a bit longer" so manufacturers build in more cushion which reinforces the customer belief, which requires increasing the cushion, - and pretty soon you're building in 100miles of "reserve" capacity?!?!?!?!? If Lexus really leaves 4gal in a 17.2gal tank (RX450h) with "0 miles to empty" showing, that's going to really reduce the "comfortably usable" range. 2gal should be at absolute least 30 miles, which seems like plenty to me.
Sigh. Distance to empty is a great feature - iff it's reasonably accurate

my rx450 was on the countdown, said 4 miles to go when i got to the gas station. only took like 15.0 gallons, holds 17.2 on my 17 rx450
this was on a cross country run, heck i backed off 10 mph to make the station, was surprised to see i had about 40 miles or more i could have gone.
