Kinda silly how they want to ban them. they are more of a safty device than somthing to help u speed. If ur doing way over the limit one u deserve a ticket, two u usually havnt got time to slow down by the time the radar tells u about it.

what they good for is if ur doing maybe just over by not paying attention or changing cd , then it will warn u, and also emergency cars and workmen ahead it warns u for which is good.
