Very interesting story..
I have to agree with TT/A on this one. There is a bit too much risk. Radar detectors are one thing. That's a cat and mouse game, but this is serious business. Just reading that article, I could think of several ways that this 'scheme' could easily be made to backfire on the user. Quick example: There are only a BILLION of those damn red light cameras. I'm sure it wouldn't be too difficult to set them up to take a picture of traffic for every time this MIRT is activated. Sure they would get plenty of pics of police and ambulances, but 11pm at night, it would probably just nab one person.
I just get the feeling that even though we think this is a dream... it really seems like a nightmare and just a bad idea.
