Thanks for the answer

In effect, the laywers were afraid for the unknown and preferred the inferiour performance of a known situation rather then risk improving things by introducing a relatively unknown situation.

Also for some reason people are expected to sooner litigate a company whose "trained" car was involved in an accident then a car company that produced an "untrained" car, even while the latter situation is most likely a more dangerous situation. As in most applications; human controllers are pretty mediocre. Alot of accidents happen because a human controller made a error or intepretated the situation the wrong way.

I'm sure that "trained" cars will add a few new error and accident modes, but the reduction in human induced accidents could be much more significant.

But it is the same thing ago; alot of world problems could have been solved already if not everybody was paying so much attention to protecting their own backsides.
