Hi everyone,
Shame about the old forum, but nvm.....
The TLDR is I was travelling South on M% - Tewkesbury, in managed section which was mainly 50mph, apart from one 40mph section which I recall. I'm adamant I adjusted my speed as I travel a lot as a contractor and 'always' use my limiter.
The only guide in the images are the lane markings (I have no idea what the yellow tram lines are trying to indicate?), so the pertinent question is what are the spacings of them? I've tried to look at the government website(s), but best I could ascertain is somewhere between 6-8m?
A transit custom SWB is 2933mm axle-axle, which appears to show my vehicle travelling around 2 x wheelbase in 0.35s, which is around 18m in 1s or 40mph.
To be travelling at 51mph as alleged, I would needed to have travelled 22.8m or ~8m in 0.35s......I think!
Is my maths correct, or am I way off with the distance?
First image, which I believe 'proves' nothing as I'm beyond the gantry:
