I don't think this distinction is morally meaningful. Do passive monitoring tasks require more discipline? Probably. Are you unable to perform them? Get another job.

How many times do you think this driver was distracted with the phone when doing their job? I bet it wasn't just this one time that they happened to crash.

Pilots crash after hours of boredom because debugging problems in the air is hard, not because they were negligent leading up to the problem (vast majority of the time, anyway). And still by and large they succeed, it just goes unreported in the news because business-as-usual. This driver on the other hand got into an unrecoverable situation because of their own behaviour.
