Are you sure that Tesla's tech is significantly better than that of a S class? The S class Benz has been at the forefront of safety tech for over a decade now; I recall it having adaptive cruise control in 2005 or so.
I didn't write significantly. Anecdotally, it is better (I own both). Highway self-driving, OTA updates, situational awareness, screens, auto Homelink, GPS air suspension, etc.
