It's not irrational at all. I drive our family 2018 Honda Odyssey, and it's already "saving me from my own mistakes" by beeping angrily when I signal for a lane change and there's someone in my blind spot. Works really well. It also has a notification light on each side of the car to indicate blind spot object presence, so I have to miss that first.
The question seems to be which is better:
1) A car very intelligently helping a human drive better.
2) Or a car mostly driving well itself but needing humans to very rarely override fatal crashes.
I prefer 1)
I'm not sure there are any studies comparing these things, since "human driving but lots of extra tech help" is harder to quantify and doesn't have all the data going back to the mothership like Tesla.
I think that 1 and 2 still can entail the same problems though. If it helps you check your blind spot you might occasionally stop checking yourself and rely on it to check for you. Then you implicitly start relying on that feature to work. It's different degrees of handing over control though.
