Even the 2 pilot at all times doesn't work even if policy. Just look at the U.S. Where it is law, and only 21% of pilots there follow/obey that rule according to the study that was posted in the other thread on the crash.
Nothing needs to change it is just a fact of life. You could find the perfect airline and then get killed on your way to the airport by a lorry driver who decided to end it all by driving into oncoming traffic
