And you are wrong again.

I wouldnāt let someoneās personal vendetta against me tarnish a whole thread. I just Block and Bye!
I have a pressure gauge and two compressors with gauges (one in each vehicle) so I check pressure with all three, and if the readings are consistent, all are accurate. Not that I do this every time but when I get a new gauge or compressorā¦
I do the same as you, but I canāt say I know for sure if any of the guages I use are actually accurate. I rely mostly on the gas stationās air-pressure gauge, b/c Iām hoping that one is tested by state inspectors once in a while. Inspectors periodically test the gas pumps for accuracy I think.
State inspecters for a station air pump !! Not a chance .
At the low price of 110/12 volt small air pumps why donāt you have one ?

Never gonna happen. Gas pumps are tested because they sell by the gallon.

Back to square one I guess.
Yes - back to square one:
There was likely a time when at least every other garage in a given town had one of these, albeit analog, mounted on a bench in the back of the workspace.
My theory as to why such an apparatus is no longer found in garages?
Simple: Consumer tire gauges have gotten incrementally more accurate over the decades, making a check station, or master gauge, necessary only on the manufacturerās premises, or in government or consumer reports testing labs.
EG: I travel back in time 50 years with my Longacre Racing Magnum series 0-60psi tire gauge, or one of Intercompās Deluxe line, to check the pressures on Elvisās limo tires, and my gauge would BE the reference tire gauge in the 1970s!
But again: You get what you pay for (put that on my tomb stone!). Longacre and Intercomp arenāt cheap, and even their mid-line Deluxe could set the average wage earner back 2 to 3 days pay.
grab a handful of the free gauge at discount tire. these have been far more actuate then buying a gauge.
A handfull ? I can see asking if you can have one for each vehicle but taking a handfull is just wrong.
And no they might be close but never as accurate as the better gauges .
Why not? One of our forum members claims that he owns 12 (or maybe it was 14??) tire pressure gauges.

Never really had a problem with tpms, pencil gauges, tire inflators or filling station gauges, Close enough for me I guess.

Yep, some folks are concerned with Ā± 2 psi, when the world is driving around at Ā±5 psi (or more) and surviving just fine in almost all cases, maybe giving up some tire wear here, some fuel economy there.

And thereās nothing wrong with doing that, if thatās what one cares about.
Well, then there are other things. I need to check the pressure in my well pressure tank. Itās supposed to be set to 2 psi lower than itās cot-on point. In this case, Iām pretty sure a difference of +/- a couple/few pounds can matter to water supply and well pump health. But IDK. Not a plumber either.

I once had the pleasure of finding out our well tank pressure was low when taking care of the property while my parents were on vacation overseas. Thankfully once i figured out what was wrong I just needed to hit the reset button and wait. Would have been easier if the part with the reset instructions wasnāt upside down. Was about to run to one of the neighbors for help when i figured out it was just the low pressure shutoff. On our 2nd pump in 45yrs.

I bought a Jaco ElitePro analog gauge off of Amazon in 2017. It is very accurate and, when it no longer would hold the pressure reading until hitting the bleed button I contacted them under their ālifetime warrantyā. They responded immediately with a fix that involved minor disassembly of the valve in the gauge, cleaning, and reassembly. It took me five minutes and it was as good as new. They were ready to ship me a new one if the ārepairā did not work.
I believe it is their cheapest model and I just checked their website and the current sale makes it VERY reasonable. As someone who used to buy a new gauge every 3 to 5 years, this one has been a pleasure.

That pressure hold & bleed feature on air pressure gauges is a relatively recent feature - thirty years against a 100 year existence of consumer tire gauges overall.
It needs to be built quite robustly in order to withstand pressure being applied and then being suddenly released. Some mfgs are good at it, some, not so much.
My experiences with it?
On cheaper gauges, I found that it lasts for a few years.
On my Meiser Accu Gage, I got five years of service before the hold feature started to fail. The pointer would slowly drop down toward the bottom stop.
On a cheap Slime dial I bought for evaluative purposes, the pressure hold failed on the THIRD tire I used it on.
On my $40 Auto Meter 2162 (0-40psi), the hold worked for six months. Now, the pointer creeps down, 1-2psi per minute.
On my $60-90 Longacre Racing gauges, the hold feature HOLDS. Losing maybe 1psi over 5-10 min.
Also, I believe that leaving a gauge with hold function at the last tire pressure read puts long-term stress and wear on the internal mechanism. So dump(release) those holding tire gauges after every reading, even if it takes an extra half-second to do so.
Plunger (pencil or stick) gauges are immune to such stresses, and can even withstand repeated drops, within reason. The index rod just sits there, at the last pressure read.
The issue with stick gauges is getting the same reading every time. I found that by slowly applying the head to the tire valve, I get a lower reading. By quickly, more forcefully pushing the head onto the valve, I can get a 2-4psi higher reading! Even with Miltonās # 921s model.
Iāve read good things about Draperās(U.K.) #51536 plunger/ stick model, and may try it out to see if repeatability improves for the extra $5 cost over the 921s Milton.
