100 year old B.C. speedster let off with a warning

In Saanich B.C. a suburb of the city of Victoria in B.C. a driver was clocked doing almost the double the speed limit in a school zone. School zone speed limits are just 30 km per hour (about 18 miles per hour).

The officer who pulled him over decided against issuing a ticket. He gave him only a warning. Why?

The officer found that the driver had just been issued a five year renewal on his driving licence. The driver was 100 years old so he had just repassed his driver's test. He had a spotless record.

Even so, at 100 surely the driver should be slowing down not speeding up. For more see this CBC article.
