The really big picture takeaway is that entire systems are becoming more centralized, brittle and with no fallback in case of failure. A large scale grid failure either as an accident or a malicious act will cripple mobility unlike ICE where in a worst case electricity scenario you can use a jug to draw gasoline from underground fuel bunks at gas stations and fill your car. Widespread use of electronic payments means that cash is scarce and in the event of a failure of the payment system, whether by accident by malicious design it will cripple your ability to buy anything.
