Why do ethical considerations need to be taken into account when designing driverless cars?

Nothing is absolute save. In the future, the cars are all driverless, if your car is driving forwards with a fast speed now, then you see a dog, you will hit a dog if you don’t stop the car, however, you are not the driver. If the self-driving program of the car only requires vehicles to obey traffic rules, the car won’t stop. That’s why ethical considerations need to be taken into account when designing driverless cars.

But I still think driverless cars are flawed. For example, you can have a look at the picture above, in the picture, we need to make a decision, whether save a baby, a male doctor an elderly man and a female athlete or save a baby and a pregnant woman(ignore the red signal). This is hard to decide, the pregnant woman may be thinking about her child’s name, she is hopeful about the future… the female athlete has great potential and she is the hope of winning the Olympic Games… the male doctor can save many people’s lives, and he has saved many people already… the elderly man might be the policymaker of a company, if he dies, there will have changes in the stock market, the company will face layoffs, many people will lose their jobs… A driverless car cannot make decision for these.
