Aside from range, charging, and being strapped directly above volatile, impossible-to-put-out compounds, most issues with EVs will end up affecting new ICE cars.
Cost-cutting is the name of the game. Just like most ICEs are FWD nowadays for both emissions and better cabin space, EVs being there means that any shared platform will end up being FWD purely to save on space.
Additionally, legislation plays a huge part in it. ADAS, Mandatory cameras, speed limit chimes and such mandates new cars on the market to have all this tech. Manufacturers don't want to have 50 independent systems they have to make communicate and individually maintain.
Instead, they'll probably have in-house ECU for basic body control, acceleration and deceleration, etc, the engine controller is often outsourced in cheaper brands (Bosch is fairly common) and the entertainment system, instruments cluster, ADAS, etc, often comes from a single manufacturer or two, Bosch is a long time maker that does it all, Mobileye does ADAS (and is what Tesla started with), Luxoft and Visteon are extremely common in cheap cars too.
Since car manufacturers are only required to provide parts for about 10 years, most governments expect old cars to die after 25 years at most. By 2035, you'll be unlikely to find any good quality, low-tech-pozzed ICE anywhere.
You'd be better off making your own car by grabbing an engine from an existing one with a Bosch control module, and getting off the shelf controllers at that point.
