That's a fallback for when you get careless or sloppy.
I don't care what anyone says, no driver out there NEVER gets careless or sloppy. Not even the likes of Alonso, Hamilton, Senna or Schumacher. Whether it be down to a momentary lack of concentration, tiredness, boredom or a stressful situation, every one of us had had a lapse, however insignificant. If you have ever exceeded the speed limit, unless you have done so deliberately, you have been careless or sloppy. That, "exceeding the speed limit", may just be the moment you trigger the camera or speed gun
Nope. Most speedometers overread by at least 10%. If your speedometer is reading 50mph you will probably only be doing 47mph. In order to exceed the speed limit you need to let the needle 'drift' to nearly 55mph. Any driver that allows that to happen is not competent.
And to trigger any kind of police action (or to get a photograph taken) you need to be going so fast that your speedometer is reading 60mph. Any driver intending to drive at 50mph that manages to trigger legal action is utterly incompetent and deserves everything they get.
I think a fundamental point is being missed here. They are LIMITS not TARGETS. I aim to drive at a speed suitable for the prevailing conditions so if, for example, children are playing by the side of the road, I will slow down. The speed limiter helps me to concentrate on important things like that.
I don't care about others attitudes, that is how I drive and don't consider myself incompetent. But neither am I perfect either. And I totally agree with Jocko's statement. Anyone who doesn't is in my mind delusional.
