According to the Japanese government, 50.4% of deadly car accidents involve old people.

The data was compiled from 2010 accidents in Japan.  More than half involved people 65 years of age, or older.  Before anyone jumps to conclusions, the data needs to be broken down.  Remember the key word here is “involved”, not “caused”.

The majority of deadly car accidents involving old people, were of old people being hit while walking, not driving (50.1% of the 50.4% total involving old people).  The number of deadly car accidents involving old people driving is 23.9% (of the 50.4%).

So basically its more dangerous for an old person to walk anywhere in Japan, than to drive.
