Road bicycle racing
In professional races, radios are used so that the team can talk to each other and the team director.  The team director often travels in a team car behind the race to monitor the whole race. The influence of radios on race tactics is controversial, and some people think radios have led to less exciting racing. In September 2009, the Union Cycliste Internationale (UCI), the governing body of pro cycling, voted to ban team radios in men's top level road racing.
