That can theoretically already happen, has nothing to do with whether a car is electric, and we already deal with something kind of similar known as "limp home mode"
It has nothing to do with the electric drive train, but electric cars are way worse in that regard. I blame Tesla for it.
Tesla essentially made the first electric car people wanted to drive. It did that with a clear inspiration from the smartphone world, hiding and locking away all the ugly internals with a slick touchscreen interface. Of course other manufacturers are going to follow the most successful player, but at the same time they don't want to alienate their already established (ICE) consumer base and its network of dealers and mechanics.
Electric cars are a clean slate and they can afford to be bold with anti-features, Tesla have shown that they can get away with it.
The mechanism to disconnect the power cord is patented, and the patent is not licensed to the end user. Using it to disconnect the power violates the patent and risks lawsuits. A copy-protection scheme is based on the AC signal sent through the power line. Cutting the power cable or turning off power is a circumvention that violates the Digital Millennium Copyright Act. Bashing the screen in creates a derivative work that infringes on copyrights held by the broadcaster and producer.
