Actually, ICE is quite significant in the degree of computerization Tesla can achieve. Since engine compartments can get very hot, ICE manufacturers have to use slower, specially hardened chips in such spaces. The Tesla cars, being EVs, don't need to do this. This results in more computing resources and less expensive components.

Granted, the other manufacturers could do this as well. But this should cause us to ask, why haven't they? Even GM and Ford haven't been able to achieve the kind of integration Tesla has. That warren of diverse microcontrollers and systems is associated with a warren of supplier relationships.

So, maybe it does have more to do with being "The Tech Car" -- but isn't that even more powerful and tied to the principle of disruption than just being electric?
