Generally, while driving my car to and fro, I’m listening to the radio on 90.1 FM WYCM, a Christian radio station located in Charlton. (Their web site is down at the moment.) Now, I’m not thrilled with wireless technologies for the most part, but the radio receiver is built into the car and I enjoy and support their programming, and the signal covers the majority of my travel area.
A trend I’ve noticed lately is that more and more people tend to want to bring their own music/talk/whatever with them in their car, which is certainly fine. However, for backward compatibility with the sound system integrated in their car (which only supports radio signals and cassette tapes, which nobody uses anymore), they hook up their portable audio player to a low-range FM transmitter, and then tune their car’s radio to that frequency. Thus, they get to hear the audio from the portable player without needing to replace the car’s integrated sound system.
