When I was in grade school every year the local cops would come to school, and play a movie about 7 monkeys riding bikes. One by one the monkeys seriously injured themselves because they were monkeying around. My favorite was the monkey who showed us how he can ride with no hands, and went down an open sewer hole. Comedy.
 When ever I hear of driverless cars this movie plays in my head. Moral of the story....don't be a slightly evolved monkey and get in the car.
