With the development of artificial intelligence, more and more car companies have released their auto-pilot solutions, and some even claimed that they will achieve Level 4 within one year, which means that we will have one big step forward towards completely auto drive. This also raises some discussion about the advantages and disadvantages. Though that may not be welcomed by everyone, I believe it will be a significant milestone in human history, because the majority will benefit from it and our society might change because of it.
