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!

No. I see something like that every year on television, but not in the real world. If you've seen something like that every year, let me ask you a question: was the gas can empty or full? Gait while lugging five gallons of gas looks very different than gait while slinging around an empty can. Then, ask yourself whether or not you (or anyone you know) carries around a spare gas can in their vehicle.
