   radiate noise. In rural areas, I can pick it up before I see the lights. At

   It's easy for a driver to get distracted by 9 m waves.

   In other words, you have no answers. Here are questions for you.   
      
   What frequency do yo intend to use? There isn't any AM channel that isn't used   
   by multiple stations.   
      
   How do you intend to ground the transmitter, so the antenna actually transmits   
   RF? There isn't enough metal in a bike frame to be a counterpoise.   
      
   What if there is a metal building between the bike and any motor vehicle?   
      
   Typical of your grandiose schemes, you are on the level of Skybuck. All mouth   
   and no practical ideas.
