one more problem... (Score 2, Insightful)

in addition to the many other problems with this that have been posted like, most people playing really loud music in a car are using a CD player and the iTrip cant overpower a radio station that is tuned in well, there is another problem.

unless you can see into the other person's car and see the radio station they are tuned into, its gonna be a real pain to go through a bunch of stations on your iTrip to try to figure out which one they are listening to. Chances are the person bothering you will be long gone before you can figure this out. Plus because this so called "hack" doesn't increase the iTrip's broadcasting power, just its range (and only slightly) you might never be able to find out what station tehy are on because as stated elsewhere, the main radio station will probably overpower the iTrip.

I think someone was just really excited that they found an antenna under the 'special tape' and this was a way to let everyone know about it.
