Car crash is the first death cause among some demographics (15-25 years old). It's almost half of total accidental death. It's almost 2% of total death. And many more are badly wounded, often crippled for life.

So I would hardly say that humans can drive cars. At least, they can't do it safely.

I got about the opposite change; when I was a 12 years old, driving looked normal to me. Something everyone does. And then I tried to do it, and realized how a split second of inattention can wreak your life or someone's else. And I looked at statistics, of cars crash being a very significant cause of death or crippling injuries. Of people having more chance to die in a car accident between home and airport than flying in the plane. And I realized humans can't drive safely - it's just something we pretend because car crash being a daily occurrence, they don't make it to the news.
