| Detectors are not 100% like you said, so unless you plan to always drive like a jerk they aren't worth a dime. Paying for a ticket and a detector that didn't give advance warning is a double waste of money. If people understood how different radar guns and detectors actually worked, they would never waste their money. You may get lucky a few times with a detector, but if you drive fast and think you won't get nailed, you eventually will. |
