My passport 8500 failed me at a critical point, when I really needed to know when I was being monitored. After I got slapped with a huge ticket I decided to just sell my passport 8500 online through an auction site and have since gone without it. I got tired of the tickets and the community service, in addition to the higher insurance rates. I have since taken a mixture of the metro and now drive a much slower car, a Honda CRV. this combination has fortunately kept me out of trouble so far. The metro is cheaper for transportation as it saves me on gas and does not allow me to speed, the slower car was unintentional but that too keeps me out of trouble. The simple fact is that the Passport cannot always keep you out of trouble and you might as well drive slower or find other measures like I did.
