It still turns you into a road hazard and puts you in a dangerous situation

How about we don't take control away from the people in the driver seat

If we can't trust them to operate the vehicle then we should not be letting them operate the vehicle

We cannot solve the problem of terrible driver training with tech

How do you know? You make assumptions about a system, that doesn't even is put in place. No car manufacture will use the forth way and risks getting sued if it doesn't work good enough.

It seems obvious that any situation that unexpectedly decreases a driver's control over their vehicle creates a hazard and becomes dangerous

This is true with any situation regardless of if the loss of control is caused by hydroplaning, slipping on black ice, an unexpected flat tire, or a speed limiting system misreading a road sign and reducing your maximum speed lower than the traffic around you

Depends on the degree of speed change. It is unlikely that it would be an emergency stop. The systems can also be deactivated, at least until the next time the vehicle is started.
