Yeah I don't get Tesla's move here. Lane Keep Assist has been a standard feature in most new cars, EV or not, starting around ~2019ish. IIRC, the EU now has regulations mandating lane keep assist in all new vehicles sold.

Heck, a cheap base model Maza 3 I rented had lane keep assist.

Tesla only stands to lose by gatekeeping what's now a basic feature behind a paywall.
