I routinely drive my Altima down to less than 50 miles Distance to Empty, sometimes near 20 miles. Been doing this for 115,000 miles, no problems. That's less than one gallon remaining (two quarts plus a couple ounces) in the tank, then I refill with about 16 gallons. You do the math on the percentage, but it's small.
I won't have a Diesel because (in random order):
Diesel fuel stinks
Diesel won't evaporate away like gas, you have to wash it off of your hands and clothes.
Most diesels are noisy
All diesels act up worse in cold weather
Diesel fuel costs more
What's with the other tank that must be filled up periodically? Exhaust treatment?
Do people idle Diesel cars / pickups for hours on end like the big trucks do? Never understood that.
Similarly, what drives me away from electric cars (again, no particular order):
Range on a full charge is poor
You can't use the full charge! Fast charging above 80% or running below 20% shortens battery life. So poor range is a lie, it's actually much lower.
Cold weather performance is exceptionally poor. Batteries don't like cold.
I'd hate to not reach my destination because I played the radio, or it got dark and I turned on the headlights.
What do I do when the government is browning out power, says to not run AC at home and not charge electric cars? Are we all supposed to stay home? My boss wouldn't like that!
Too many electric cars just catch fire for no apparent reason. Yes, Tesla too.
Electric car fires are extremely difficult to put out, a handheld extinguisher won't do anything noticeable.
Oh, yeah, the electric cars all cost more, too. I'm price sensitive and about to retire, which will make me more so.
