Not the smartest thing but I once went 40+ miles after it showed 0 range. Danger is my middle name. LOL

Well, maybe not so much an issue for the southerners, but for people living in climates with real winters, leaving your tank empty allows more water vapours to build up inside your gas tank, which will eventually form ice crystals and cause cars to fail to start or start rough on the coldest days(aside from battery issues). Once the weather thaws out, these cars usually return back to completely normal state.
The gas is supposed to have addictives to prevent freezing, but when you're running your tank low, it means the concentration of those addictives is going to be relatively lower compared to water as well.

My understanding on the fuel pump issue is that it's not damaging to the pump to run your tank low, but it is potentially damaging to run OUT of gas. The pumps are cooled by the fuel, but not by being submerged in it. They are cooled by having fuel pass THROUGH it. So as long as you haven't actually run out, you shouldn't have damaged your pump.

I always run my tank low and have never experienced a fuel pump failure.
These days, cars are so reliable that as long as you use them in the way it was intended for, you should not have any problems. No where in the owners manual that it says that you shouldn’t run the car with low fuel all the time.
You can call these myths, preventative measures, safe guards.... blah blah blah. Same goes for changing motor oil ever 3,000 miles! Those quick lubes got us convinced on this interval for decades!
Let’s no also forget about the medical journals. One day, we read that it’s bad to consume wine. In the next journal, a new reasearch suddenly comes out with the opposite....... stating that a glass of wine each night is actually good for our body! Go figure.
Let’s just enjoy our cars. Being paranoid while driving a Lexus doesn’t seem like a great match. After all.... we’re not driving a German-mobile. No need to worry about where the fuel level is .... that is, unless you are bone dry.

That's different than @eddie420 post though. He's got 2 gallons left when the range shows 0 miles. My low fuel light comes on when the range shows ~30-35 miles remaining. That would indicate the low fuel light comes on with more like 3-4 gallons remaining.
So there’s likely 2 1/2 to 3 gallons left when the light goes on.

I had never heard of the fuel pump inside the gas tank concern. I'm now concerned about doing that on hot days (many during DC summers) since the near-empty gas tank and hot summer day may be a bad combination. Except for some more than normal O2 sensor issues with my old RX 300, I don't recall any other fuel pump, filter, etc. issues I've had after more than a decade driving RXs. Anyone have specific examples of required fuel pump replacement that the mechanic tied to running the gas tank low? There's no warning against doing that in the manual.
BTW, the best gas elated advice I learned a long time ago was never fill your tank up while a tanker truck is servicing the station. Since the fuel going in the station's tanks is churning up sediment/crap on the bottom of the station's tanks that have been there for many years - decades in some cases, just drive to the next station or come back the next day.
