Because the technology isn't/wasn't there and is "good enough" as it is. But it doesn't compare to the efficiency of millions of years of evolution. Eg. Feathers for flying + flexible bone structure and absorbing skin for water pressure. I will react with the question: although we can dive and fly. Wouldn't it be better, if we adapt to nature's evolution? Eg. Put on a feather- suit, jump start the engine to get off the ground and then float to the destination and only let the engine kick in when we need to go higher/land? Riding on earth's natural wind and sparing fuel resources ( going off topic here) On topic: ML/AI should be able to datafy all related information that human eyes perceive. And those datapoints need to be handled by every situation that occurs. The article clearly shows that this is not the case yet. While a brain has more adaptability, Tesla should be able to counteract this with more data of the vehicles that drive around.
