TIL: The US is going to stop producing pennies. I understand that the recommendation was for merchants to simply round prices either up or down. Haha, just kidding about that down part.

Who pays with cash for any transaction over a few bucks? And how many sub-$5.00 purchases do you make?
I've been saying this for years.
The penny has been underwater for decades.

That's how it's worked here, we got rid of the penny years ago.
They do actually round down, but as Duke says, who uses cash any more? I don't use it for any transactions now if I don't have to.

Me.

Me too. Every month, Mrs and I each take a modest cash allowance for incidentals. She also pulls the monthly grocery budget in cash. Visually confirming how much cash is available before payday does a lot to prevent careless spending.
The "shut off the fuel pump if there's no spark" logic on an '85 Volvo 240 is inside the fuel pump relay.
I'm guessing it's an RC timer circuit that gets topped up at each spark and drains far enough to cut the relay if there's no spark for X time.
Explains how you can get some weird behavior out of a fuel pump old enough to contain middle-aged capacitors.

It doesn't shut the fuel pump off. If the ecu doesn't see a crank sensor signal, it has no reason to turn the fuel pump on.
I cannot count the number of times I have told people with no fuel pump operation to check for spark first.

Evil businessman would destroy his reputation over three cents. Dirty rotten businessman. They are all evil, and kidnap children to sell into slavery.
Cone on, man.

They've been talking about stopping production in the 1980s. The idea was, when the Lincoln penny was 100 years old in 2009, that'd be it.
In reply to Streetwiseguy :
I know that's normal, and that's modern, and that's what's expected. Even my Megasquirt did that. That's also why the revelation was worthy of a TIL entry after a bunch of time with a car that *did* run it's fuel pump, but died irregularly, and a bunch of time reading the wiring diagram, mostly to understand why the advice on Volvo forums that a fuel pump relay could cause this sort of unevenness could be true, because replacing the fuel pump relay did fix an intermittent dying issue (to the extent that you can prove a negative).
The ECU on an L-Jetronic 2.2 '85 Volvo doesn't get involved in the fuel pump as near as I can tell. There are two inputs to the relay (not counting the turbo overpressure switch the manual shows as an optional item and which this NA car doesn't have, EDIT: which if present would be inline in the path to ground; we just ground); one's ignition switch, the other is coil.
EDIT: I'm done digging through the wiring diagrams to understand a problem that appears to be fixed. I'm guessing it's possible that the power from the ignition switch is a pass-through originating in the ECU (switch powers up ECU and also passes output back through to one relay input, making that disconnectable with the key if the ECU freezes 'on')... Weirder, it looks like '85 should be the first year that *didn't* use a pulse-counting fuel pump relay according to https://www.240turbo.com/fuelpumprelay.html, even though the move from K to LH was a few years earlier. The 2.2 diagram pointed to a couple of links in there show a 4-pin fuel pump relay which is clearly not what's present on this '85, while the Bentley manual's diagram shows in the '85-specific wiring diagram the 6-pin relay and connection to tach signal. We're well into year-to-year variations now, but I'm certain enough that my amusing-to-me discovery stands, even if it's just a holdover from the K-Jetronic and even earlier LH cars.
