The port in the car is probably only USB2. It will be a standard chipset sourced externally and done as cheaply as possible. Which is also probably why it only supports one device as well - that's how it was years ago and they haven't changed it (it was like that in my BMW X3 of 2016 and my BMW 320 of 2013).
It is what it is - let's just live with it.

No doubt you're right
@Alan Sh about it being implemented with single client legacy USB2. Definitely
nobody will desolder & replace the USB chipset from their Tucson just to connect multiple devices and get faster charging, so of course we have no choice but to "just live with it"!
I'm under the impression that we are all here, to share information and hopefully glean some, in return.
So when someone says "
Also how is not having the newer USB C input really any kind of problem?", I take that as an opportunity to provide information and context to enlighten that person, particularly when I've opined that the absence of it is somehow materially deficient. I certainly didn't expect my explanation to be met with vitriol, but I suppose not everyone's on an even playing field.
Here's a link on Reddit discussing which cars have been implemented with USB-C (dating back to MY 2018), showing many 2020 models with this feature. This is why I believe it's a serious omission in the 2022 Tucson, actively marketed by Hyundai as a technology showcase.
If nothing else, I hope I've provided factual and supportive information on why USB-C is desirable.
