Maybe we are looking at different cars, I only really am exposed to American cars. Any vehicle I have been in made after 2021 have integrated most things into the infotainment system. Which are now also integrated into the operations of the cars.
And ICE vehicles rely, quite heavily, on the hundreds of moving parts that have been engineered for 120 years. Nothing mechanical can really regulate managing the charge rate of the battery, or are able to calculate the necessary changes in power to each motor, or managing any kind of safety system. As some of those things have been added to ICE vehicles, the lack of buttons has been notable.
