You are not responding to what members are pointing out to you.

You have described a perceived danger yet many of us haven't experienced your concern despite driving that stretch of road regularly.

It is quite clear you do have difficulty with it and one can only conclude you need to improve your driving ability to cope.

Call it patronising, rude or whatever you like.

However, although I don't know you I wouldn't wish ill on you and I hope you heed the good advice offered to you.

I tend to stick to the inside lane and use lane discipline, people forever have a go at lorry drivers (I'm not one) but they are far better drivers than the vast vast majority of drivers so tend to spot trouble well before others.

Plus the speed most of them travel at 56mph on the nose is ok for the 50mph speed signs so most don't need to adjust their speed

My figure of 20% is actually over generous, the speed camera will normally be set at 56mph + before they take a picture.

Assuming your speedy displays 70mph, your true speed will likely be nearer 66mph. The difference from true speed of 66mph to 56mph is nearer 15%.



I could adjust my speed for the above figures from siting a gantry speed sign without using the brake

Car speedos are better than they where in the 80's. The speedos on our cars, (well the newer ones) agree with the sat nav, to within 1mph. So any lorry driver behind me will be adjusting his speed down to 50, (well 49), or overtaking if he wants to.

Well the poster in question seems to be one of those idots you see in front who's constantly speeding up, braking, speeding up, braking, unable to anticipate the road and conditions ahead.

All the vehicles I drive (Oldish) are out by circa 7%

Which is why it's bad advice to keep telling drivers of modern vehicles that all speedos underread. Most, but not all, are accurate nowadays.
