We already had one! Dashboard indicator lamps have been an international standard (ISO 2575) since 1982.

Yes, it is. But the key word is "if". The product folks involved in making these UI/UX decisions were more concerned with whether or not they could (read: "chimp attract" for "feature parity" to "drive sales") than with whether or not they should (read: "should we be manufacturing two ton death machines that act like nannies?"). Where is the research that provides the answers to the questions "how likely is it that the driver isn't aware of how much fuel is in the vehicle?", "are our customers really as stupid as we think they are?", or even "what's the downside of training our customers to accept a more mindless state of existence while piloting giant metallic flesh-tearing bone crushers packed full of explosive hydrocarbons and squishy humans?"

> The general public though… uh oh!

You can come down from your ivory tower at any time. We have tacos down here and we all enjoy them.

To quote the late, great Lou Holtz, "they put their pants on the same way we do". I don't think there's ever been a time in all of my years on this planet that I've gotten into a car to go on a highway journey of any length and not looked at the fuel gauge. Oftentimes, my passenger will even ask me how much gas is in the tank. Glancing at the fuel gauge should be the first thing that any motor vehicle operator looks at when climbing into the captain's chair. Maybe I'm at that stage of life where I'm no longer capable of comprehending the manner in which the younger generations experience the world, but getting into an automobile and driving off without knowing how much fuel you have is like walking out the front door without confirming that your shoe laces are tied.

This constant othering of "the general public" without any research to back it up really grinds my gears, to use a contextually appropriate idiom. Please stop.

I wanted to acknowledge the user likely has above average faculties. “why would anyone use Dropbox,” “you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem”.

Zero times I’ve run out of gas. Don’t we pass someone walking with a gas can on the highway every year though? Dangerous, slightly safer if you use the fuel delivery service from AAA.

I admit I do not know quantitatively e.g. how popular that included-with-membership free 5 gallons (AAA).

Probably a million features I’d spend money on before trying to “fix” the fuel light though!

I don’t look at the field guage when I get into the car and start it - I already know about how much fuel is in the car since I drove it last.

Additional context:

Non-trivial for me to re-create dropbox.

I want a unique quiet ding when the gas light comes on and when I turn the car on with low gas.

Thank you for challenging me! Have to reflect.
