As a practical matter this is reinforced as well by the need to still carry a driver's license. In principle the government could offer a secure digital ID, but it doesn't. Phone payment also isn't at 100%, so a backup credit card also still a good idea.
So it's necessary to have the ability to have a card on hand anyway, and at that point it's not much of a stretch to have a couple. Either via a phone case or whole wallet, but it's not like someone can (legally) just take their phone with them when going for a drive. Keeping the keycard along with license and credit card is still fairly minimal (phone digital wallet can consolidate a lot of fat card packs beyond those).
I guess the bigger risk is that while I always at least take my wallet with me in the car, I don't always take it with me out of my car while I always have my phone. Might be nice if Tesla had at least an option for some sort of fallback auth mechanism built into the car itself, be it keypad or biometric. The ones in phones are pretty good and are a pretty tiny item on the BOM, in a $35k+ vehicle seems like there should be room for it as an option?
Maybe that's overthinking it though, not like regular cars tend to have those either. Sometimes people just lock themselves out with regular keys too and that's that.
