Teslas from four years ago with Intel Atom processors and HW3 are already getting different and lesser updates than new Teslas, without any hardware upgrade plan in place.
A Tesla you buy right now is running HW4 which is inferior to current Cybercabs and HW5 has already been announced.
Except for maybe the '58 Thunderbird, but that was rectified in '61 in my opinion.
Although to be fair the vibecoded packages are probably higher quality than what Hyundai would've shipped.
The problems being:
1. It didn't always recognize a destination as a fast charger
2. The built in nav is missing recently opened fast chargers
3. It only does this if you have the "preconditioning" setting enabled, but the car has a bug where if you use the (maybe only US version) Hyundai app to change the AC or DC charge limits it unchecks that setting.
4. I prefer Google Maps to the built in nav
Even so, I have a button in the battery settings which can start the preconditioning whenever I want to. It's been a fantastic car, but I am envious of your DCFC capabilities. But not of your ICCU. :-)
And tracks you everwhere you go, resulting in that data being available to hackers, marketers, and any sleazeball that wants to extort you by suing you.
Not unique to tesla, of course, but a property of all those 'well designed modern cars'.
