I'm really looking forward to it whenever I do take delivery. Here in AZ, the state has partnered with Apple to support storing your Drivers License within Apple Wallet. (No official release date besides early 2022 last I checked)
That means I can now have my car key, driver license, and credit cards all on my phone. I'll have no need for my keys or my wallet when I'm going out any more! At least for small trips until I get more comfortable…
