Re: The Jeremy Clarkson Effect...
Exactly Psyx, sometimes the weather conditions mean that driving at a speed anywhere near approaching the speed limit would be dangerous.
But you can control the vehicle and drive at or under the posted speed limit. If you don't, then you have to live with the consequences.
I've used the navigation feature on my smartphone once in the last 2 years. I don't even know whether it offers speed trap notices. I usually know where I am going and I look around me.
