Everyone's car already knows what chargers they can use. The card doesn't route you to incompatible chargers. This is a solved problem. It sounds like you just don't have an EV.
It's more a note for any apartment dwellers thinking "I see Tesla chargers all over town, I could buy a 2025 Equinox (or whatever) with NACS and swing through the one on next to my office when I need to. If it's a v3 or v4 that's true, if it's an older station it's still only for Teslas.
I think you're overestimating normal car buyers, as EVs continue to shift from early adopter novelties into the mass market. People will see a charger and expect to be able to pull up and charge there, like they've been doing with gas stations for decades.
SAE is thankfully working on universal plug and charge standards which will be a huge help for the other problem - the mess of different apps for each charging network. Because just providing a credit card reader like every gas pump ever was too hard.

So if you buy a new EV thinking "I know where the nearest Tesla chargers are" you could be in for some disappointment. Check the map first: https://www.tesla.com/findus?filters=nacs_superchargers
It's a worse problem in some areas than others. For example, all 9 supercharger locations in South Dakota are Tesla Exclusive.
