Isn't Mercedes' L2 system non-upgradable, though? i.e. people with Merc's L2 system today won't be able to upgrade to L3+ later on, they'll need to buy a whole new car - right?
I bring this up only because I bought my X in 2018 with FSD prepaid - it's 5 years old now, and thanks to the gratis retrofitted computer upgrades it has the same level of FSD functionality as a factory-new Model Y purchased today - and I value that level of commitment to their carbuyers - whereas all the other carmakers I've ever dealt-with are the type that gladly charg $lots just for annual updates to the navigation maps SD card.
(I don't want to be seen defending Tesla, let alone Elon Musk here, but Tesla has avoided plenty of the worst practices of traditional automakers (okayokay, excepting the heated-seats thing).
