My son told last year, when he went to a convenient store  near his apartment, he saw a car crashed into the store.

One staff of the store was apparently broken waist bones and brought into a hospital. It seemed that old man made mistake by pressing the accel pedal instead of the break pedal.

In Japan,  a lot of similar car accidents happen. It cannot be helped that human's ability become dull with aging.

In 2018, German  big company Audi reportedly will release the world's first full self-driving car. It might be very expensive. I hope we can get such cars by a reasonable price in the near future.
