Brazil's 98FM lets bikers hijack its airwaves to keep oblivious drivers at bay.
Cycling is dangerous activity in many cities, but one of Brazil’s most popular radio stations is trying to make it a bit safer. If drivers can’t see a bicycle in their blind spot, maybe they can hear it. "Safety Bike Radio" is a portable radio transmitter for cyclists distributed by 98FM, a station in Minas Gerais, about 250 miles north of Rio de Janeiro, and its agency Isobar Brazil. There’s a good chance any given car on the road will be tuned to 98FM, so when a bike gets within 30 meters, drivers hear prerecorded warning messages rather than music. Cyclists can also record their own personalized messages for drivers, and DIY bikers can build their own units from downloadable instructions.
