Answer this letter to Ann Landers: I’ve read your column for ages and almost always agree with you. One subject on which we do not see eye-to-eye, however, is senior citizens driving. According to the Memphis Commercial Appeal, recent statistics by the National Highway Traffic Safety Administration indicate that drivers over 70 were involved in 4,431 fatal crashes in 1993. That is far fewer than any other age group. The 16- to 20-year-olds were involved in 7,711 fatal crashes. Elderly drivers also had the lowest incidence of drunk driving accidents. Now, will you give seniors the praise they deserve?
