That's true. Humans are bad at this task. On the railways they have a problem with this too, "Lookout" seems like a ludicrously easy job, but it's basically impossible because you must pay attention to an incredibly boring thing for hours or your friends might die. Getting rid of human lookouts should be a priority but it feels easy and so it's hard to motivate this.
This is also a big challenge for airline pilots. The planes mostly fly themselves these days, and most takeoffs and landings are uneventful. Being an airline pilot involves an absolutely massive amount of business as usual and preparation, for the very rare times something happens and you suddenly need a team of very focused experts to solve a difficult problem in a stressful environment.
At least they have simulators. Last time I saw a driving simulator I was a teenager.
Imagine you had to pass a simulator test involving responding to ANY crisis while driving before your license would be renewed. Rates of driving would plummet.
I bet most drivers don’t even correctly handle a flat tire on the expressway.
