The following appeared in a letter to the editor of the Balmer Island Gazette.
"The population of Balmer Island increases to 100,000 duing the summer months. To reduce
the number of accidents involving mopeds and pedestrians, the town council of Balmer Island.,
should limit the number of mopeds rented by each of the island's six moped and bicycle rental
companies from 50 per day to 30 per day during the summer season. By limiting the number of
rentals, the town council is sure to attain the 50 percent reduction in moped accidents that was
achieved last year in the neighboring island of Torseau, when Torseau's town council enforced
similar limits on moped rentals."
The author of this editorial recommends that to reduce accidents involving mopeds and
pedestrians Balmer Island's city council should restrict moped rentals to 30 per day, down from
50, at each of the island's six rental outlets. To support this recommendation the author cites
the fact that last year, when nearby Torseau Island's town council enforced similar measures,
Torseau's rate of moped accidents fell by 50%. For several reasons, this evidence provides
scant support for the author's recommendation.
To begin with, the author assumes that all other conditions in Balmer that might affect the
rate of moped-pedestrian accidents will remain unchanged after the restrictions are enacted.
However, with a restricted supply of rental mopeds people in Balmer might purchase mopeds
instead. Also, the number of pedestrians might increase in the future; with more pedestrians,
especially tourists, the risk of moped-pedestrian accidents would probably increase. For that
matter, the number of rental outlets might increase to make up for the artificial supply
restriction per outlet--a likely scenario assuming moped rental demand does not decline.
Without considering and ruling out these and other possible changes that might contribute to a
high incidence of moped-pedestrian accidents, the author cannot convince me that the
proposed restrictions will necessarily have the desired effect.
