We want physical buttons and dials, not touchscreens. We don't want our location and driving data recorded and sent over the internet to their servers. We want reliable engine starting, battery life and locks, not "smart" features which can fail due to software updates or being away from cellular reception for too long.
I'm not sure there's a single car being manufactured today that can compete with a car from 10+ years ago for a use case like "Will my key unlock the door and start the engine, after my car has been parked at a forest trailhead for a week".
