As it stands today, unmanned vehicles (entirely operated by AI with no human intervention) still has shortcomings from accidents or collisions. Also, how would society react to AI being the driver? If there’s no steering wheel on an entirely AI operated car: how can you override its protocols when it becomes rogue? There are “self driving” cars, but how many use that as their main mode of transportation than driving a car?
The technology for it exists, but remains rather niche since there’s still more cars driven by people than cars operated by AI. Do YOU want to replace your own car with an AI operated one or rather keep one meant to be used by humans? As of now, it’s rather rare unless you happened to spot one whilst on the road. Most car dealerships only sell “normal” cars intended for humans, even Teslas still require a human driver.
The more skills people acquire and use throughout their lives, the better. I prefer people behind the wheels of cars. Some automated commuter trains already exist, and that's cool, but driving is a skill that should be kept by the masses.
