FSD has routinely plowed into children, emergency vehicles etc.

You are using this word 'routinely', but I do not think that it means what you think it means.

Can you give me, say, 10 incidents of this? Of a Tesla confirmed to be on FSD driving full speed into a child, emergency vehicle, etc?

FSD used to 'routinely' be overly cautious and slow down when not necessary, but I don't think it's driving into things.

I'd also point out the driver remains responsible for the car and an eye movement camera prevents distracted driving, but I digress.

Other companies have implemented these more limited systems (that often include better sensors such as lidar) not because they can’t do it but rather because they are more cautious about brazenly lying to people about the capabilities of their system.

Other companies simply have less capable systems.
If I go and buy a current product Tesla, I can have it drive me home and chances are I won't have to touch any controls. In a few cases, new production Teslas literally deliver themselves to the new owner's driveway. Can any other automaker say the same?
