But the level of automation right now in aircraft is dangerous: enough that the pilot’s job is really boring, not enough that the pilot isn’t occasionally needed. We all know how that works out in practice.
The excellent safety record of scheduled commercial flights contradicts your claim that the current level of automation is dangerous. We have proof that it works well in practice.

Etc....
The bored pilot problem is only going to get worse as technology marches forward, even if the fatality rate keeps going down.
On the other hand we don't know yet whether self driving cars will actually be safer. They're only used in very limited times and places so there's no way to do a fair analysis.
In cruise, there's not much to do in an aircraft and minimal oversight by the pilot is easily accomplished. Then, during the arrival (and during the departure), the workload is quite a bit higher, meaning the job is anything but boring and it's easy for the pilot to remain engaged.
