It's a cognitive bias in all of us, including the lawmakers approving the use of self driving cars.
I've driven cars for 20 years and my driving has (imo) improved over that time.
I'm at a level where I don't see a reason for me to get into any serious accident by my hand. It's just not going to happen * fingers crossed *.
I know my driving style. I know I'm a safe driver.
Now, why would I give that security over to "FSD", which is clearly a decade (if that) away from being user-ready?
Don't get me wrong, as said, certain automation is cool ... stop/start in heavy traffic, lane assist, cruise control, crash avoidance even ... but beyond that? I'm A-ok ... don't need to introduce the risk from half-baked code (no offense, but that's true at this stage) or AI where we don't really yet know what the output will be (despite being impressive "most" of the time).
Now, I'm speaking about me. You can do what you like. And if you're willing to hand over the reigns of your life to some beta programme, be my guest. Just don't drive in the opposite direction to me for, say, another 10 years. Thanks.
At it's best, and most of the time, an automated system will be a far superior driver than me.
However, coding error and AI hallucination mean I will not touch these systems until extremely proven. And we're at least 10 years from that, if at all.
(note I'm talking about true FSD not the current nonsense. An experience where you can have hands and eyes off the road. With the current nonsense, the novelty is cool, but when that wears off you're just a manager of your car. The worst of both worlds. You have to pay attention to the road and get none of the pleasure of driving. What a fail).
