Advanced Tech
EVs for the most part have been designed from the ground up to be just, well, EVs. As a result, engineers have been able to take advantage of the newest technologies and not carry along the baggage of having to use the "parts bin" methodology of new car design (ie use parts from previous ICE cars as much as possible in EV cars). If I recall correctly the only ICE car that seriously diverted from this methodology was the Chrysler 300M, although I'm sure some old tech snuck in even then.
So, what Advanced Tech is introduced or at least massively enhanced in EVs? Here are the basic categories:
AI
Lane Centering and Follow (Tesla Autopilot)
Smart accident avoidance (FSD Beta Deer Avoidance , Autopilot Examples)
Smart Wipers and High beam control
autonomous driving on city or country roads, marked or unmarked (FSD Beta)
FSD Beta as good as a student driver? (spoiler, it passed but still needs improvements)
Fast and Smart Charging
Connected Car

Computer Control vs Mechanical Controls
Improved Reliability. Mechanical controls (knobs, dials, levers) wear out or break
Fixes to car functionality (range, performance, and even braking distance)
New features or functionality added via over the air updates
thermal battery management octovalve
high efficiency motors and inverters and The Plaid Motor Surprise
improved battery chemistries and battery design (frightening economics of Teslas 4680)
Slide from a Sandy Munro round table with other auto industry experts.
Tesla leads in core efficiency but newer cars coming out should start competing.
