Commodity computers and touchscreens weren’t in many cars 15-20 years ago. Cars with features like seat cooling and heating were premium trim level versions, now those are more widespread. Wiring for cameras? Wiring for lidar, radar, and all sorts of other sensors? The sensors (and presumably their required computer system) themselves? All add weight. Also, using steel as opposed to advanced, lighter and more expensive materials, the larger crumple zones (safety features) weigh more.
