In itself it is not that bad, only it is mainly regulations that hold things up very much (and in Europe just cause a complete stop)
In America there are already several 100% autonomous trials underway that the public can simply participate in in the form of autonomous taxis etc.
However, in Europe there the rules are such that for just changing lanes (by a computer) there must already be so much space in front of and behind the car that it can practically only be used on the most empty roads. Or you should find a minimum distance of 55 meters to a vehicle behind as normal…
You have the same joke with rules regarding automatic steering, an autonomous car is simply not allowed to make a lot of practical bends in the current road system according to European law (for example an entrance or exit from a highway).
Making a real autonomous car on the basis of current European legislation is simply life-threatening, because the average user then intervenes to change jobs because the computer is not allowed to do it by the rules.
The same with many turns etc, if the user does not take over the wheel, an autonomous EV must simply come to a standstill in a random turn.
It is expected that these rules introduced in 2019 will be reversed in the future if the EU car manufacturers come along with regard to autonomous driving, but until then it is only life-threatening to have an autonomous car that complies with EU rules.
See also UN/ECE R79 regulation to find the rules.
