I have FSD too, and my opinion is that although it takes unsafe actions almost on a daily basis, most of these errors are minor, easily rectified by me the driver, and most of the time it drives just fine, in fact better than a human driver. I witnessed FSD avoiding me a collision by responding faster than I could have by auto-braking when another driver ran a red light.

FSD doesn't need to be perfect to avoid accidents. In fact, if it was too perfect I'm afraid I could become very inattentive at the wheel.
