This tragic coincidence occurred in 1975. Seventeen year old Erskine Lawrence Ebbin was struck and killed by a taxi while driving a moped. This was exactly 1 year after his 17 year old brother was killed by the same taxi, holding the same passenger, driving the same moped, at the same intersection.
This terrible quirk of fate earned the 17 year old a place on newspapers from both sides of the Atlantic. It is a crushing reminder of exactly how small our world is, of how even death seems to be losing its creativity.
It seems like coincidences are actually pretty common on the road, for more see here
