That feels like we're stretching the claim a whole lot. The "basic concept" of a Tesla isn't that different than a Model T but I think most people would reject the claim that cars haven't really changed much.
Road design and laws have mostly stayed the same in the past 50 years. How about controls (pedals, wheel, etc) - more or less the same as well (subject to regulations).
There are similarities in your example. The fact that Tesla has autopilot and is an EV represent two of the biggest moves away from traditional car concepts. If you used an ICE car I would say the concepts haven't changed much.
