Things may have changed, but i doubt it. Many years ago i drove a 69 chevy 3/4 ton 4x4. I put a 4" lift on it and very large tires, resulting in my speedometer being off rather drastically. I tried using that very excuse and was told almost exactly what SVTballa was saying, that it's my responsibility to ensure i am driving a safe vehicle. I was given a "fix it" ticket and still got the speeding ticket.
Any police officer who bothers to take the time to write a ticket for speeding is going to say basically the same thing. I used my visual skills to observe this vehicle going at approximately 80 mph, i then utilitzed my "radar gun" and got a reading of 80 mph. This occurred in an area where the posted speed limit is 65 mph. Yes, the driver of the car is guilty of driving over the speed limit. Your best bet is to pay the ticket with a smile and try to keep closer to the posted speed limit.
