EVs aren't loaded with high tech components. Particular manufacturers like Tesla might appear to go that way, but if you drive an EV by anyone else the exterior, interior and software isn't especially any different to any other vehicle of the same age regardless of propulsion. In some cases the car is even built on a vehicle platform suitable for EV or ICE variants of the same vehicle - most of Stellantis cars are that way. And EVs do have lower maintenance because they don't have mechanical parts that need replacement - timing belts, clutch / gears, cylinders etc.
Tesla does tend to make people make blanket assumptions about EVs though. e.g. Tesla does gigacasting to cut down on structural parts in the frame of a vehicle and maybe people assume this is the way it has to be. Except this isn't an EV-specific technology and other automakers are already beginning to copy them.
