Seriously. People really need to understand that CTCSS and DCS aren't actually privacy features, but convenience features for filtering out _other_ people's transmissions a user isn't interested in. It's the exact opposite of privacy. I guess the marketing as "privacy codes" worsens the situation.

I just got my GPRS radio license and this was a really strange phenomenon to encounter. Apparently the FCC doesn't allow actual encrypted comms in this part of the spectrum, so the "privacy" codes, like you said, are really more just convenience codes, more noise cancelation than anything for privacy or security.
It was weird trying to explain this to my family, too. Basically just had to tell them "Nothing you say is private, and you should all say my call sign at the end of each transmission." We all felt like dorks, but it was super convenient in a place with no cell service.

I got my hands on one of those cheap UV-K5 Radios and the first thing I did was try to listen in to one of my FRS Radios and discovering all their channels & sub channels/privacy codes.
Discovered this list while learning & researching:

#6I'm really happy about the firmware updates.
When Flipper Zero was crowdfunded, the deal was that the tool will be available once the hardware is good enough to fulfill the promises. And so the software will be updated later.
I'm happy that they keep they promises.

Get an itinerant frequency -- $300, requires no coordination, and you can encrypt your comms.
One of the (ham) radio clubs that I'm a member of does this as a benefit for the group, and it's something that's nice to have: I can give my wife a radio and not worry about what she may or may not say if we have to take two separate cars when we road trip.
I've been meaning to do the process myself, but, I haven't had the time (and honestly, I'd want someone else to do the paperwork for me so I'm more likely to pay someone else to do it) recently, but, this might be the thing that prompts me to go and do it.

Cool!
What sort of radio do you use?
My friend and I tried to do -- the two of us in different cars driving down the same stretch of highway this with GPRS radios and very quickly we were not able to pick up the other's broadcast. We assumed it was that we didn't have big enough antennas and were not using a repeater.
Note - others were driving we were each a passenger in our respective cars.

Interesting! I was under the impression that the FCC was actually somewhat strict about part 90.35 eligibility, in that you have to provide fairly detailed specifics of your business use case or how you fall under the various educational/nonprofit exemptions, and that if you told them you wanted it for personal use or supplied a thinly veiled excuse they'd tell you to get lost. Maybe that understanding is outdated. I can imagine a HAM club having an easier time justifying that than you would as a random individual.
